The reclusive pedal builder discusses the origins of his famed Centaur overdrive, the more affordable new KTR design, and how one pedal can inspire so much adoration and disdain.
If you've spent any amount of time on guitar-gear forums, you know they can often devolve into pretty abrasive battles of opinion. Even when a thread starts out with the best of intentions, it's not uncommon for it to morph into the online equivalent of a mythical Hydra. Forum administrators attempt to clean things up and lock out the more abusive commenters, but once they cut off one of the creature's heads, two more appear.
Of all the forum topics that can inspire such heated debate, few inspire more passion, awe, and vitriol than a guitar pedal named after a different sort of mythological creature. Launched in 1994 at the front end of the modern-day boutique-pedal boom, the Klon Centaur overdrive was immediately met with critical acclaim. So much so that it's ironic how much the pedal named after the half-human, half-horse creatures from Greek legend has since developed such a complex mythology of its own. And the fact that this seemingly mundane, 3-knob stompbox is used by such high-profile players as Jeff Beck, John Mayer, Joe Perry, Nels Cline, and Matt Schofield only compounds matters. Never mind the fact that the majority of the circuit comes encased in epoxy.
We recently spoke to Klon's Bill Finnegan about the origins of the Centaur, his new KTR design—which made a (naturally) limited debut in October of 2012—and how an overdrive pedal can fetch more than $1,000 on the used market and inspire such emotionally charged reactions.
Birth of a Centaur
In the 1980s, Bill Finnegan played in a band where he plugged his Telecaster straight into a Twin Reverb turned up as loud as the soundman would permit. In bigger Boston-area clubs, the Twin's volume would be at 6 or sometimes even 7, but in smaller places Finnegan could usually turn it up to only 3 1/2 or 4. The latter still sounded good, but not as harmonically rich as when the amp was working harder. Although it didn't occur to him at the time, a pedal that would give him the sound of a cranked amp is exactly what he needed.
Finnegan recalls that, in 1990, guitarists began chasing after out-of-production Ibanez Tube Screamers in droves. He'd heard about a guy who was selling two TS9s, and—hoping one of the little green pedals would help make his Twin sound like it was at 6 when it was only at 4—he went to check them out. It immediately became clear that Tube Screamers were not for him.
Finnegan built Centaurs—around 8,000 in total—by hand, on a cheap folding card table in a succession of small apartments for 15 years.
“[The TS9] compressed the transient response of the original signal a lot, had a midrange character I didn't like, and subtracted a noticeable amount of bass response from the signal as well," he explains. The same seller also had a TS808 that he wasn't selling. And, though Finnegan thought it sounded a little better than the TS9s, he still felt it had the aforementioned shortcomings. What he really wanted was a big, open sound, with a hint of tube clipping—a sound that would make you unaware a pedal was involved.
That's when Finnegan starting looking into creating a new design that would meet those criteria. He recruited a friend who'd just graduated from MIT with an electrical engineering degree. Though both had day jobs, for the next couple of years they got together once a week and tried to push the ball down the field. Within the first year, they'd developed prototypes that were much closer to what Finnegan wanted than a Tube Screamer, and various guitarists in the Boston area encouraged them to go into production so they could buy their own. But Finnegan felt the circuit could still be improved, so he and his partner kept working.
Eventually, the MIT friend bought a house in the suburbs and the distance made it harder to work together. Finnegan later partnered with the late Fred Fenning (who tragically passed away in a plane crash in the mid '90s)—another MIT grad whom Finnegan says was brilliant and very determined. Although Fenning had never designed an audio circuit and had no real interest in music, he was exceptionally good at finding ways to give the circuit what Finnegan thought it needed at any given time. Finnegan says Fenning deserves a lot of credit for the circuit in both the Centaur and its successor, the KTR.

The entire design process took four and a half years, and when the pedal debuted at the end of '94 Finnegan was soon very busy trying to keep up with the demand—building, testing, and shipping the pedals as a single-man outfit.
Evolution of the Legend
From that point on, demand for Centaur pedals grew. Finnegan says he typically worked 55–60 hours per week in effort to keep turnaround times as short as possible, though he was hindered by the fact that the circuit was very labor intensive and time consuming. He also says it was more expensive to build than most other pedals due to the fact that everything from its cast enclosure to its knobs, pots, and sheet-metal bottom were custom crafted. Finnegan estimates the aggregate cost of a Centaur as seven to eight times that of a pedal built with off-the-shelf parts.
“For the last seven years or so of Centaur production, the retail price was $329," says Finnegan, “and to be honest, my profit margin was not very sensible—no real business person would have considered, for more than a moment, doing what I was doing for the return I was receiving. Also, given that I live in Boston, it was impossible for me to hire people and expand: Real estate here is in short supply and very expensive, so there was no possibility of my renting commercial space to set up an actual shop."
Finnegan built Centaurs—around 8,000 in total—by hand, on a cheap folding card table in a succession of small apartments for 15 years. In addition to the modest returns from his efforts, Finnegan says he felt immense stress as he tried to oblige those who wanted a Centaur but didn't want to pay the inflated price used specimens were fetching because of the 12- to 14-week turnaround time for a new one. It gradually became clear to Finnegan that the situation was unsustainable.
“These two photos show my testing jig for Centaur boards, with one of my experimental boards on it," Bill Finnegan shares. “The experimental boards have sockets for every component in the circuit, which enables me to listen to any particular component and then swap it out for a substitute while keep everything else the same. This experimental board is the one I used for developing the KTR. Unlike the Centaur which had through-hole components with leads, I wanted to use surface-mount components for the KTR, which meant that my assistant, John Perotti, and I had to spend an enormous amount of time soldering through-hole leads onto hundreds of very small surface-mount components so that we could evaluate them and choose the ones that would make the KTR sound the same as the Centaur did."

“I was going to have to kill it before it could kill me," Finnegan recalls. In 2008, he began working on a ground-up redesign that had to meet the following criteria: It had to be straightforward to build, so that any good contract manufacturing firm would be able to do the job easily and well. It had to be rugged and reliable. It had to be a design with no hookup wires whatsoever, and with a modular footswitch assembly so that faulty footswitches could be replaced in a few minutes. It had to be considerably smaller than the Centaur. Except for the all-important clipping diodes, it had to have surface-mount components, which take up less space on a board than traditional through-hole components. Finnegan also wanted to prove—to himself and to those who said it couldn't be done—that, with careful component selection and smart board layout, he could design a successor that would sound exactly the same as the Centaur.
“This turned out to be quite a challenge," Finnegan says. “My assistant, John Perotti, and I spent almost two years listening to different surface-mount capacitors in various places in the circuit before I felt this had been achieved." Lastly, he wanted the new unit to be visually unique—a tall order, given that the unit would be housed in a standard enclosure.
I don't have any overall preference for single-coil guitars or humbucker guitars myself. I like pretty much everything under the sun in the way of electric guitars, and over the years I've owned a bunch of very different ones.
The one new feature Finnegan wanted to incorporate was a switch that enabled the player to choose the buffered output of the original Centaur or a true-bypass output. “Without the buffer there is a very noticeable degradation of the signal due to the capacitance inherent in guitar cables," says Finnegan, “but some people prefer it, so I wanted to provide that option in the new unit." He quickly adds, “My good friend Paul Cochrane—of Tim and Timmy [pedals] fame—was the guy who designed the switching circuitry, so a tip of the hat to Paul."
It took a long, long time to finish the KTR. And though Finnegan says it was much more difficult than he expected, he feels it has achieved all of his design objectives. “It sounds the same as the Centaur, takes up considerably less space on a pedalboard, is less expensive, and it's distinctive aesthetically—it's got the Klon thing going on." He laughs, “Whatever the Klon thing is."
You obviously have high expectations from your designs, though you're also perplexed by the reactions it inspires. What do you want people to see in Klon?
What I want people to expect from me and from Klon are designs that are exceptional in the literal sense of the term—designs that are conceptually sound and well executed. Designs that are unique and not to be expected from any other designer, no matter how talented.
When you were designing the Centaur, did you begin with any assumptions about players who'd be interested in it?
I was working from the assumption that there were a lot of guitar players with really good guitars and really good amps who were looking for an overdrive pedal that—whether it was adding dirt or not itself—wouldn't mess up what they already had and liked. Given the popularity of the Centaur and now the KTR, I would say that this has been borne out.
In your opinion, do the pedals work better with single-coils or humbuckers?
Neither. I don't have any overall preference for single-coil guitars or humbucker guitars myself. I like pretty much everything under the sun in the way of electric guitars, and over the years I've owned a bunch of very different ones. Each of them has its own particular thing going on, and when I was working on the design of the circuit I was always thinking about how it could be more effective in preserving and accentuating the essence of whatever instrument it was receiving the signal of.
What can you tell us about Centaur units that occasionally turn up on eBay with the claim that they are “new, with full warranty"—are they fakes?
I have a very close friend who is a single mom and whose job doesn't pay all that well. Every now and then she needs a little help, financially. I'm aware of what the used units are selling for, so at some point after I discontinued the Centaur it occurred to me that—if and when she needed me to—I could build a Centaur and give it to her to sell on eBay and use the proceeds to keep going. This has worked really nicely, and I'll continue to do it for as long as my old Centaur parts last. Since I discontinued the Centaur, a lot of people have asked me whether I'd consider building one for them—sometimes offering me pretty substantial amounts of money—but I'm not going to do that. The only Centaurs I build anymore are the ones I build for her, and I don't make or collect a single cent from them.
Klon builder Bill Finnegan wanted to include this text—which refers to the dialogue surrounding his famed Centaur design—on the casing of his new KTR pedal. “It's a wry observation that I can't be held responsible for the overheated emotions that have been introduced into various Klon debates since the earliest days of the Centaur," he says. “I knew that in using that text I'd be stirring things up some, but I thought it would be interesting and fun to see how, in reacting to it, people would self-select into either the 'love it' or the 'hate it' group."

Do you think Centaurs will retain their high value now that the KTR is available?
Yes, in general I think they will. They're collectible and—with the one small exception I just mentioned—no more will be built, unless I'm very mistaken. For almost everyone, the KTR is a much more sensible option now: It sounds the same, it's much smaller, it's way the hell less expensive—$269 retail—and you don't have to worry about losing something that's worth $1,000 or $1,500 or $2,000 if it's stolen. On the other hand, the Centaur has something of its own that people really like and are willing to pay serious money for. The design has achieved a certain status—I would use the analogy of old, custom-colored Marshalls. I have two small-box, 50-watt Marshall Lead heads—model 1987s: One is a black-Tolex, aluminum-panel head from 1970, and the other is a red-Tolex, plexi-panel head from 1969. They have the same circuitry and sound almost identical, but of course the red one is worth way more than the black one. I like cool, distinctive things as much as the next guy, so I'm not in a position to criticize someone for being willing to pay more than I myself would, or more than most people would, if they want it that much.
What are the demographics of the typical Klon user?
It seems to be more or less everyone. Baby-boomer guys who are still only interested in the music they grew up with, but also a lot of younger, indie-rock people, and also a number of musicians whose work is more experimental and can't be easily categorized.
What can you tell us about the germanium diode you like so much in your circuits?
In 1993 and '94, when it was clear that Fred and I were getting close to producing what I thought was the full measure of what our circuit was capable of, I started buying quantities of every diode I thought might be at all suitable for the head-to-toe pair that clips the signal, except for when the circuit is in clean-boost mode. This was pre-internet, so I was going to the public library, looking up distributors in the Thomas Register, and then calling those distributors to find out what they had—email was still in the future then! I started out ordering both germanium and silicon diodes, but pretty quickly I began concentrating on the germaniums. Usually, though not always, they sounded more natural to me than the silicon ones did. After months and months of listening, I felt a particular new-old-stock germanium diode sounded best in the circuit, so I thought I should buy as many of those as I could afford. Eventually, I found a distributor that had a significant quantity of them. They were stocking them for a huge OEM, who—without any warning, I gather—stopped using that part. I bought them all at a good price. The distributor was thrilled to be able to sell them and not have to eat them.
Does the KTR have the same diodes?
Yes, the KTR has the exact same NOS diodes as all Centaurs did.
Since I discontinued the Centaur, a lot of people have asked me whether I'd consider building one for them—sometimes offering me pretty substantial amounts of money—but I'm not going to do that.
What is it you like about the sound of that diode when it clips?
It's a little more complicated than that, because the diode clipping happens on top of some op-amp clipping in the main gain stage. So it's op-amp clipping, then diode clipping. But to answer your question, this particular diode in the head-to-toe pair in the circuit just produces a very natural-sounding distortion in terms of the harmonic response. It's not harsh, but it also doesn't round off the highs excessively. It doesn't compress the signal as much as many germanium diodes seem to, but on the other hand it provides a little bit of what—to me—is exactly the right kind of compression.
Which other pedal makers are using this particular diode?
To the best of my knowledge, no one. It's a part that's been out of production for decades now, so even if someone else could identify it, I seriously doubt they'd be able to find any—I've tried a number of times myself.
So what are you working on now?
Lately, I've been focused almost entirely on putting together a good long-term arrangement for production of the KTR. This kind of thing has always been more of a challenge for me than it seems to be for anyone else, but I admit that I do have requirements—particular things I insist on—that few, if any of those other people have, so I guess that the increased difficulty is to be expected. I'm not saying that my stuff is necessarily higher quality than anyone else's, but rather that my criteria are somewhat different and that therefore the process is necessarily also somewhat different.
What is the current availability of the KTR?
The unit should be widely available—through dealers both here in the U.S. and in various other countries—by the time this interview is published. Hopefully by then I will have found time to get some kind of updated Klon website going, which of course will have contact info for the current dealers.
The top of the KTR features some text that's apparently causing controversy with some buyers: “Kindly remember: The ridiculous hype that offends so many is not of my making."
Lots of people got the point that I was trying to make and really enjoy the text, while other people find it off-putting or even insulting. It's a wry observation that I can't be held responsible for the overheated emotions that have been introduced into various Klon debates since the earliest days of the Centaur. I knew that in using that text I'd be stirring things up some, but I thought it would be interesting and fun to see how, in reacting to it, people would self-select into either the “love it" or the “hate it" group.

What does the future hold for Klon?
I've been thinking about this quite a bit lately. Part of me wants to work on design ideas I have—finish those designs to my satisfaction—and then make the resulting products available. The other side of me wants to either refrain from working on those ideas or work on them, finish them to my satisfaction, and then not put the resulting products out. As you may or may not know, many unscrupulous people have expropriated my hard work on the Centaur and KTR circuits and are selling pedals that incorporate my circuit—and in at least some cases, they're making a lot of money. And apparently there is nothing I can do about this from a legal standpoint.
Quite aside from the money they're making from my work, there's the question of what those pedals sound like. My understanding is that a number of those people are claiming their versions sound “identical" to mine, which—for reasons not only pertaining to the clipping diodes you asked me about—I think is very unlikely. Whatever expertise those various people may have, I'm going to go out on a limb and state my belief that it's not likely to be a good or sufficient substitute for the experience I have with the circuit: I co-designed it, I've hand-built and listened to about 8,000 Centaur units, I spent two years working hard to make sure the KTR would sound the same as the Centaur, and I've put almost 25 years of my life into it. If those other guys' pedals don't sound right, then of course Klon's reputation—and my reputation as someone who cares deeply about the quality of what goes out under the Klon name—will inevitably take a hit.
So my feeling is this: If any new product I come out with will be ripped off immediately after its release, and if unscrupulous people will again be making money off of my work, and if on top of that Klon's reputation and my own personal reputation will be at risk every time someone decides to put out his own version of one of my designs, then where is my incentive to release anything new at all? Over the past few years, I've talked with a number of other pedal designers about this stuff—good people who design their own circuits, and whose circuits have also been ripped off—and we all agree there is now an enormous disincentive for any of us to create and release new products.
From what I understand, a lot of the people posting on various online forums seem to feel that it's a wonderful thing for the pedal consumer to have more choices—how could that be bad? Here's how it could be bad: Maybe talented pedal designers—originators—will simply stop designing pedals and take their talents elsewhere to apply them to the design of other classes of products that can't be ripped off quite so easily.
Top 5 Klon Myths
Gear forums are regularly aglow with all sorts of comments about Klon. Here are the most common misconceptions.
- The Centaur is a slightly tweaked [insert name of extant pedal here] circuit. According to Klon's Bill Finnegan, “it's a much more complex circuit than the typical overdrive/boost circuit. These claims stopped almost immediately after it was reverse-engineered in 2007 and a schematic was posted online."
- Certain Centaurs sound better than others. Finnegan says he's heard this claim about earlier units, later ones, gold ones, and silver ones. “The fact is, under the hood they're all basically the same. In 1995 I made three small changes: I added a resistor to give the circuit some protection against a static charge delivered to its input—a change that has no sonic effect. I also had the circuit board redesigned with a ground plane for better grounding—again, no sonic effect except the potential for a little less hum. And I added a resistor to give the circuit a very small amount of additional low-mid response—I wanted it to have a little more roundness when used with, say, a Strat into a Super Reverb. I made no other changes."
- The KTR doesn't/can't sound as good as the Centaur. Finnegan says this claim arises because the KTR uses surface-mount parts while the Centaur (and most other pedals) use through-hole parts. “For two years my assistant, John Perotti, and I listened to hundreds of different surface-mount parts throughout the circuit," Finnegan explains. “While it wasn't an easy or pleasant process, we both feel—and now a lot of other people feel, as well—that I achieved my design goal: With careful component selection, the KTR sounds the same as the Centaur."
- You have to play really loud for the Centaur or KTR to sound good. “You need to have the output knob high enough that the signal hits the front end of your amp harder than your bypassed signal would," says Finnegan. “In other words, you need to use the unit as an overdrive in the literal sense of the term." The assumption here is that users are pairing the Centaur or KTR with an all-tube amp. “It's always a good thing if your amp is turned up enough to get the harmonic response and distortion that are engendered by tubes clipping and output transformers saturating. This is true whether you're playing through a 4-watt or a 100-watt amp."
- Certain clones sound “exactly the same" as a Klon. Finnegan's contention is that, given several factors—especially the rarity of the Centaur's germanium clipping diodes—it would be extremely difficult to create an identical-sounding overdrive/boost.

A terrific twosome or a terrible twinning? It all depends on how you tame your treble.
Rein in those icy high frequencies with these handy tips.
Classic vintage Fender amps are renowned for their clean, shimmering tones. However, dialing in the “sweet spot” isn’t always straightforward, especially when you're playing on a new or borrowed amp. Pair these amps with Fender guitars—also known for their brightness—and the combination can sometimes result in ear-piercing treble and overwhelming volume. An amp that’s too powerful or an unsuitable guitar pairing can easily derail the musical moment you’re trying to create. So, controlling treble is crucial, particularly with louder amps.
In this article, I’ll share my experiences with Fender amps and how I’ve tamed treble issues through guitar tweaks, speaker swaps, amp modifications, and pedals. My goal is to help you achieve those glorious vintage Fender tones without losing your ears—or your audience—in the process.
Backline Bargaining
I’m extra cautious about bringing my brightest Strats or Teles to gigs with rented backline amps. Newer Deluxe Reverbs, for example, can be particularly tricky with dialing in a smooth tone. These amps often feature bright ceramic speakers and the EQ options are limited—there’s no bright switch to dampen the top end and no mid knob to add warmth.
Here’s what I do: I start by turning down the tone knob on my Okko Twinsonic overdrive pedal, which is very transparent. My old Ibanez Tube Screamers naturally rolled off much of the high end, making them easier to pair with brighter amps.
I also adjust the microphone placement set up by the sound crew. The tone gets brighter the closer the mic is to the center of the speaker cone. I angle the SM57 slightly and aim it closer to the outer edge of the cone, leaving a 3–4 cm gap from the grill cloth. Larger 12" or 15" speakers are more forgiving in this process, while smaller 10" speakers are less so. I’ve encountered challenging amps, like a Super Reverb loaded with 10" JBL speakers featuring aluminum dust caps. These amps sounded much harsher through the PA than they did on stage, making mic placement even more critical.
Dimming the Bright Caps
Bright caps are key components in shaping an amp’s treble response. On the Deluxe Reverb, the bright cap is always enabled, which can make brighter guitars sound harsh, especially at low volumes or when using fuzz pedals. Cranking the amp helps by adding more upper mids to the mix.
For my own Deluxe Reverbs, I sometimes disable the 47 pF bright cap or, more often, install a 25k mid pot on the back panel to add warmth. It depends on the tones I’m chasing.
Smaller amps like the Fender Champ and Princeton don’t have bright caps, which naturally gives them smoother tones. But if they sound too dark or muddy, you can add a bright cap. I installed a 100 pF bright cap on my 1966 Princeton Reverb (which has a Jensen C10N speaker from the same year, though not original to the amp). After experimenting, I settled on a 47 pF cap for just the right amount of clarity.
If you’re up for a bit of DIY, experimenting with bright cap values can significantly shape your tone. Black-panel and silver-panel Fenders typically use 120 pF bright caps, with exceptions like the Deluxe (47 pF) and the Princeton and Champ (none).
Guitar Tweaks for Warmer Tones
Your guitar’s setup can also make a big difference. Thin strings combined with pickups set too close to the strings can result in a thin, overly bright tone. Here’s how I address this:
● Lower the pickups slightly. I start with a 2–2.4 mm gap on the high E string and 2.4–3.3 mm gap on the low E, measured between the pickup pole and the string when fretted at the highest fret. Then, I fine-tune by ear to balance output across pickup positions.
● Use thicker strings for a warmer, fuller tone. I tune my guitars down to Eb to deepen the sound and increase sustain. Keep in mind, though, that this can create a looser, flabbier bass response on smaller amps.
● Hotter pickups add mids and bass, naturally reducing treble dominance. Alternatively, lowering the resistance of the volume pot can smooth out the tone by filtering high frequencies. However, changing pot or cap values will alter how your guitar responds when rolling down the tone or volume knobs.
Speaker Swaps
Finally, and perhaps most importantly, speakers play a huge role in shaping your tone. Swapping speakers or experimenting with extension cabinets is one of the most effective ways to adjust treble, mids, or bass. I’ve written extensively about this in previous articles, but it’s worth emphasizing here: The right speaker pairing can make or break your tone.
I hope these insights help you conquer any treble troubles and coax balanced tones from your Fender amps. Happy tinkering!

Each night of a G3 tour ends with an all-out jam and on Reunion Live, the trio hits classics by Cream, Hendrix, and Steppenwolf. “When you hear each guy solo, you can hear how we’ve changed through the years,” says Vai.
Joe Satriani, Steve Vai, and Eric Johnson reflect on their groundbreaking tour with a fiery live album that took nearly 30 years to make.
“When you’re young, you’re attracted to all these [guitar] ideas—do this, do that,” says Eric Johnson. “You’re like a sponge. If you get yourself out of the way, get rid of the ego, and stay open, you remain a student your whole life. But at the same time, you get to the point where you’re like, ‘There’s only so much time, and I don’t need to learn this and that.’ There are things that Joe [Satriani] or Steve [Vai] do that I’ll never be able to do.”
Some guitarists would find that notion depressing—of finally extinguishing the naive youthful fire to master every technique on their instrument. (It’s probably easier to find peace when you’re one of the world’s most revered players, with platinum sales and Grammys on your résumé.) But when Johnson looks at Satriani and Vai, his fellow virtuosos on the 2024 G3 reunion tour, the idea of “letting go” puts a smile on his face.
“Although we stay open, we define some of our journey,” says Johnson. “We can’t be everything to everybody. Then you start appreciating what someone else is doing even more.”
That sense of refinement is crucial to the story of G3, the triple-guitar tour conceived by Satriani and launched alongside Johnson and Vai in 1996. Over the years, the event has morphed to incorporate players from just about every style: from blues-rock (Kenny Wayne Shepherd) to prog-metal (Dream Theater’s John Petrucci) to hard rock (Uli Jon Roth) to the eerie soundscapes of King Crimson’s Robert Fripp. Far from a rote shred-fest, it’s a celebration of the electric guitar’s unlimited possibilities. And Satriani’s been thinking a lot about that idea following the G3 reunion tour, which ran for 13 dates last January, spawned a new concert album (Reunion Live), and will eventually birth a documentary helmed by his son ZZ.Recorded live at the Orpheum Theatre in Los Angeles, Reunion Live documents the culmination of a 13-date tour that brought the trio together for the first time since the original tour in 1996.
“He had an interesting idea for a film,” Satriani says. “Our first G3 show happened the week he turned four, and we decided we were always going to take him with us. He wanted to do a film not only about that and about G3 but also his whole point of view growing up with a very strange father and this community of guitar players. He wanted to know their perspective on guitar playing and music and this life he’s been a part of.”
The younger Satriani grew even more ambitious, proposing that the OG G3s [OG3s?] get together for another tour. “ZZ wanted to see what it was really like, after decades of traveling with me and the different bands, to get onstage and play,” Satch says. “It all sort of happened in those last two shows at the Orpheum in Los Angeles. ZZ came on and played a song, and that sort of brought the film full-circle—from the four-year-old to the 32-year-old playing onstage with his dad. The [as-yet-unreleased] film has really developed into this epic story about guitar players. Eric and Steve have been so generous with their time, letting ZZ interview them about music, guitar, and what it means to them. But that’s really how the whole thing got started this time around.”
“30 years later, you can really see more of the dynamic difference in our go-to notes and riffs. Joe is more Joe now; Eric is more Eric now; and I’m more me now.”—Steve Vai
Reunion Live unfolds like the actual G3 shows, with miniature heavy-hitter sets from each artist (you get Vai’s “For the Love of God,” Satriani’s “Surfing With the Alien,” Johnson’s “Desert Rose”), followed by a trio of generous, triple-guitar cover-song jams—in this case, ripping versions of Robert Johnson’s blues staple “Crossroads,” Steppenwolf’s open-road proto-metal anthem “Born to Be Wild,” and Jimi Hendrix’s hard-psych powerhouse “Spanish Castle Magic.” The latter, fronted by Johnson, is the album’s centerpiece: 11-plus minutes of instrumental fireworks that perfectly showcase each player’s distinct flavor. Toward the end, the groove lays back into a quiet, funky simmer—the perfect platform for an onslaught of tasteful flourishes and ungodly shredding.
Back in 1996, the trio barnstormed across the country and laid waste to guitar nerds everywhere with a scorching version of Zappa’s “My Guitar Wants to Kill Your Mama.”

“The thing I liked about that [choice] was that it’s very common to play a Hendrix song in a jam, but most people play the usual suspects,” says Vai. “Eric’s Hendrix catalog runs deep, and he’s played ‘Spanish Castle Magic’ on multiple occasions, and I’ve played it in the past. When it came up on this G3, I was very excited because it’s a great song to play. It’s just got a great feel to it, and the groove for soloing is very open. I was very happy to see that.”
“I hate the word ‘competition.’ But if we didn’t want to challenge each other, we wouldn’t have agreed to do the tour.”—Joe Satriani
“I remember doing so many cover songs over the past few decades, and every once in a while you come up with an all-purpose song that anyone, from any walk of life, can come join you on,” says Satriani. “And then you have these other songs that really shine a light on an individual’s foundation as a player and some of their early inspirations. I know that all three of us were so into Jimi Hendrix. I love doing that song. I’d do any Hendrix song. Eric and I have a lot of experience going out with the Experience Hendrix [tribute] tour. He figured into our early musical lives—even before I played guitar, I was a big Hendrix fan.”
“Crossroads” is also fascinating on many levels. Sure, it’s hard for any good rock band to screw this one up, and it could be the most obvious pick for any guitar jam, but the song’s simple blues structure also allows for a delicious whiplash, magnifying the vast differences in tonality and note choice between each guitarist.
“At first, when ‘Crossroads’ came in, I was like, ‘OK, it’s this classic rock song.’ But once you’re onstage and playing it, the riff is so great,” says Vai. “It’s robust. When you hear each guy solo, you can hear how we’ve changed through the years. Not just us—any guitar player who sticks with their craft goes through various evolutions into different directions. Some can stagnate, but you’re usually inching toward something different. Most of the time physicality is involved in that. When I hear ‘Spanish Castle Magic’ or ‘Crossroads,’ the stuff on this jam, my ears are listening to 30 years ago, in a sense, when we would trade. Today, 30 years later, you can really see more of the dynamic difference in our go-to notes and riffs. Joe is more Joe now; Eric is more Eric now; and I’m more me now. I’ve abandoned trying to sound conventional in any way.” The more they sound like the definitive versions of themselves, as on this G3 tour, the more in tune with each other they seem to be.Joe Satrian's Gear

“I would listen to Joe and Steve, and I would marvel at the guitar playing and the consistency of how great it was, but for me, it was [also] an opportunity to look beyond [it],” says Johnson. “It was a bit of an epiphany doing this tour because I tuned into the energy they had, the songs they were writing, the sounds they were getting, the shows they were doing. It even made the guitar playing more interesting because there was another dynamic I was tuning in to more. Not that it wasn’t always important, but as you get older, you try to see the whole hemisphere and what that means to the audience. It’s a win-win because it doesn’t take anything away from the guitar—it makes it more interesting to have encased in that bigger thing. I noticed that more this time, which made me feel good.”
“We can’t be everything to everybody.”—Eric Johnson
The G3 tour, and particularly the encore jams, are fascinating at the conceptual level: taking players largely renowned as soloists, and forcing them to share stages and trade licks—working to compliment each other’s playing instead of simply flexing their muscles and drawing on some primal competitive drive.
“The ego is the definition of competition,” says Vai. “Its perspective is, ‘How do I stack up? How do I rise above? How do I sell more, make more, have more, be more than anyone else?’ This is nothing personal to me—this is in the collective of humanity. Ego can wreak havoc in your life and cause a lot of dysfunction and stress. You don’t know it because you’re unconscious of the way the ego can be competitive. More in my earlier days, in the background, there was a perspective of competitiveness. This doesn’t just go for G3, but it was never in a playing way. I felt, ‘My playing is so abstract and bizarre that there’s no one else doing this weird stuff.’ Of course, this is still ego.”

“But when it came to Joe, it was a very different dynamic because he was my [guitar] teacher—he taught me how to play,” remembers Vai. “Joe was my mentor. I admired him. We were joined at the hip throughout our careers. In the earlier days, you listened to the other guy, and there’s the perspective. One is a very egoic perspective, which sees things as competition. The other perspective is, ‘What can I learn here? What can I get from this that’s going to improve my tools?’ Boy, there’s plenty of that in every G3 tour, every situation I’ve ever been in. But it’s a perspective only you can choose. The feeling of competition, I don’t like it. If someone is selling more records or playing faster or tastier or their songs are better, it behooves me to see how I can gain on a personal level from that. If I was the coach of a basketball team, I’d say, ‘It doesn’t matter if you win this game. It’s not as important as doing your very best.’ In reality, the only one you’re ever competing with is yourself—your bar.”

Satriani shares a similar sentiment—that being “complimentary” in a project like G3 is a real talent and a gift. Working on the documentary has put him in a retrospective mode, thinking about past tours and how they’ve worked to be more expansive and, perhaps, even provocative in their presentation.

“Yesterday I was searching for an original print of a photo from [the G3 tour] in ’97,” he says, “where Robert Fripp was opening the shows, unannounced, hidden behind a wall of gear. That was his request—to play as people were filing into the venues. I found this great photo of Robert onstage with his guitar and four-year-old ZZ standing next to him holding a plastic pail—I think it was at Jones Beach. It reminded me of how crazy the notion was at the time of Robert joining up with the tour. But he was so excited about it and wanted to do it. We had fantastic times traveling together and hanging out backstage and getting to know each other on that particular tour, and that set the tone for me—knowing that, not only did I have comrades like Eric and Steve, who felt the same way that I did about collaboration in a live setting, but now there was Robert and Kenny Wayne Shepherd, and the concept of G3 started to really catch fire. It was really heartwarming to know that this sort of gunslinger attitude that existed in the ’80s about guitar players could be challenged. We could create something really inclusive about different styles and generations of players and take it on the road. That came back to me when I saw that photo.”
“I hate the word ‘competition,’” Satriani says elsewhere, surveying G3 history. “But if we didn’t want to challenge each other, we wouldn’t have agreed to do the tour. We get to hear each other’s sets, which is great—we don’t often get to do that when we’re off on our own tours. And then we get to stand next to each other and see what just pops out of nowhere, what each artist decides to throw out as an improvisation. Every night is a once-in-a-lifetime thing. If you can somehow work that into your musical life, you’re really lucky—so I count myself really lucky.”

Meet Siccardi Number 28: a 5-ply, double-cut solidbody tribute to Paul Bigsby’s “Hezzy Hall” guitar.
Reader: Mark Huss

Guitar: Siccardi Number 28
May we all have friends like Ed Siccardi—along with a rare stash of tonewoods and inspiration to pay tribute to a legendary luthier.
I have too many guitars (like at least some of you I’m sure), but my current No. 1 is a custom guitar made for me by my friend Ed Siccardi. Ed is an interesting and talented fellow, a retired mechanical engineer who has amazing wood and metal shops in his basement. He also has an impressive collection of tonewoods, including rarities like African mahogany and some beautiful book-matched sets. He likes to build acoustic guitars (and has built 26 of them so far), but decided he wanted to make me an electric. The fruit of this collaboration was his Number 27, a Paul Bigsby tribute with a single-cut body—looking very much like what Bigsby made for Merle Travis. Note that Bigsby created this single-cut body and “Fender-style” headstock way before Gibson or Fender had adopted these shapes. This was a really nice guitar, but had some minor playing issues, so he made me another: Number 28.
Number 28 is another Paul Bigsby tribute, but is a double cutaway a la the Bigsby “Hezzy Hall” guitar. This guitar has a 5-ply solid body made of two layers of figured maple, cherry, swamp ash, and another layer of cherry. The wood is too pretty to cover up with a pickguard. The tailpiece is African ebony with abalone inlays and the rock-maple neck has a 2-way truss rod and extends into the body up to the bridge. It has a 14" radius and a zero fret. Therefore, there is no nut per se, just a brass string spacer. I really like zero frets since they seem to help with the lower-position intonation on the 3rd string. The fretboard is African ebony with abalone inlays and StewMac #148 frets. The peghead is overlaid front and back with African ebony and has Graph Tech RATIO tuners. The guitar has a 25" scale length and 1.47" nut spacing. There are two genuine ivory detail inlays: One each on the back of the peghead and at the base of the neck. The ivory was reclaimed from old piano keys.
This is Number 27, 28’s older sibling and a single-cut Bigsby homage. It’s playing issues led to the creation of its predecessor.
I installed the electronics using my old favorite Seymour Duncan pairing of a JB and Jazz humbuckers. The pickup selector is a standard 3-way, and all three 500k rotary controls have push-pull switches. There are two volume controls, and their switches select series or parallel wiring for their respective pickup coils. The switch on the shared tone control connects the bridge pickup directly to the output jack with no controls attached. This configuration allows for a surprisingly wide variety of sounds. As an experiment, I originally put the bridge volume control nearest the bridge for “pinky” adjustment, but in practice I don’t use it much, so I may just switch it back to a more traditional arrangement to match my other guitars.
