Let’s go under the hood of these legendary rockabilly machines and explore different ways to enhance a passive guitar system.
Welcome back to Mod Garage. Before we start, some good news! After finishing the relic’ing series, I was able to raise $650 from our Harley Benton guinea-pig guitar in an auction. The money went to our local animal shelter for cats and dogs, to help pay some vet bills.
This month, we’ll take a closer look at the typical wiring you can find in almost every Gretsch guitar. Since 2002, the Gretsch guitar company has been a division of Fender Musical Instruments Corp. But the company has a long history. It all started in 1883 in Brooklyn, New York, when a German immigrant from the town of Mannheim named Friedrich Gretsch started his own shop to make banjos and drums. Sadly, Gretsch died in 1895 at the untimely age of 39 during a visit in Hamburg, Germany. His 15-year-old son Fred (the Americanized version of “Friedrich”) had to run the company. In the 1930s, Gretsch started making guitars and the company had their first heyday. Like many companies during WWII, Gretsch had to stop production of instruments to help in the armament industry. After the war, the two sons of Fred Gretsch (Fred Jr. and William) took their father’s place and started making instruments again. In 1948, the Gretsch Broadkaster drum set was their best-selling item, and the start of another story with a certain Leo Fender offering an electric guitar with the same name, only spelled slightly different.
With the emergence of rockabilly and rock ’n’ roll in the ’50s, Gretsch guitars became popular in the hands of players like Chet Atkins, Eddie Cochran, Cliff Gallup, Duane Eddy, and even Elvis Presley. Later in the game, George Harrison, Brian Setzer, Malcolm Young, and many more became popular Gretsch players.
Sidenote: In 1999, Gretsch took over the Bigsby company, which was their exclusive hardware supplier since 1951. Instruments featuring a Bigsby tailpiece, like the White Falcon, Country Gentleman, Nashville, Duo Jet, etc. are real guitar icons today.
The wiring concept of Gretsch guitars is unique and noticeably different from that of most other companies, offering a volume control for each pickup along with a master volume control. This wiring is combined with a pickup-selector switch and a tone control in basically three versions:
“The interesting part is the arrangement of the volume controls—it’s been said that this was a suggestion from Chet Atkins.”
1. Master tone control (with or without no-load pot)
This is what we know from a lot of other guitars sporting a master tone control for all pickups: Sometimes a no-load pot is used to get rid of the pot’s load when it’s fully opened. Gretsch typically uses 500k audio pots and .022 µF tone caps.
2. Two-way tone switch
There is no tone pot, but there’s a switch that activates two different tone caps as a kind of pre-set tone. Gretsch typically uses 500k audio pots, as well as a .012 μF and .0039 μF (3900 pF) tone cap on the tone switch.
3. No tone control at all
It is what it says: There is no tone control at all with 500k audio pots for the volume controls.
Use whatever tone cap you like best. The 500k choice for the tone pot is a good working solution in a passive guitar circuit. On my own Gretsch 6120, I decided to use 3300 pF and 6800 pF caps on the tone switch, and it works fine for me.
The interesting part is the arrangement of the volume controls—it’s been said that this was a suggestion from Chet Atkins. Having a volume control for each pickup is common on other guitars, like on a typical Les Paul. But the combination with a master volume control is rare … and the source of some unwanted effects. Let’s have a look at the typical Gretsch volume wiring scheme (Fig. 1). I decided to use the one without tone control because this is the basic wiring and can be found on the 6122 Country Gentleman. The wirings with a tone control are identical regarding the volume controls.
This arrangement in a passive guitar system will result in a loss of tone because of two reasons:
1. The three volume pots will drain a good portion of high-end to ground when rolling back the volume, which is the nature of the passive beast.
2. Long shielded wire runs are used inside the hollowbody Gretsch guitars, adding capacitance to the system, resulting in even more high-end loss.
Even with the pickup height adjusted correctly, the loss in high-end is clearly noticeable, so let’s see what can be done. For some players, this is no problem at all and part of the tone. If you’re happy with the way your guitar sounds, there’s no reason to change the system. If you want a clearer tone with more high-end definition, you have the following options.
If you don’t want to convert your Gretsch guitar into an active system to get rid of the high-end loss, you’ll need to compromise by adding a treble-bleed network to the volume pots. We talked about this sometime ago in detail [“Mod Garage: Deep Diving into Treble-Bleed Networks”].
Selecting the right treble-bleed network is a matter of choice. What works for me might not work for you. Maybe you like some more high-end when rolling back the volume than others or vice versa. With the typical Gretsch Filter’Tron pickups, I like a 470 pF cap with a 150k resistor in parallel. Try this as a starting point and see if you like it. In theory, you’ll need a treble-bleed network on all three volume controls, which gives you a wide control regarding sound. In my own 6120, I use different treble-bleed networks because I want more high end from the neck pickup compared to the bridge pickup. I’ve also seen configurations with a treble-bleed network on the two volume controls for the pickups and without one on the master volume control. Personally, I don’t like this configuration. Using one on the master volume and not on the two controls for the pickups will have a better result.
You see, it’s a wide field of experimentation, but it’s worth the effort. While you’re in there, I recommend changing the 500k audio volume pots for 250k audio pots to benefit from the much better taper in a passive system. The difference in high end is minimal (if audible at all), and you can compensate easily with the treble-bleed network by choosing slightly higher values. I did this in my 6120 and the difference was huge.
“Don’t underestimate the time you’ll need to get the electronics of a hollowbody guitar out and back in. Even on a good and clear day, you can’t do this within 30 minutes, so don’t hurry.”
Don’t underestimate the time you’ll need to get the electronics of a hollowbody guitar out and back in. Even on a good and clear day, you can’t do this within 30 minutes, so don’t hurry. If you’ve ever changed the electronics inside such a guitar, you know what I mean.
Gretsch uses shielded wires inside, but sadly, the quality is only average. The wire has a high capacitance, and, especially inside big hollowbodies, you can find up to 2.5 meters (about 8.2 feet) of it, which is a real sound killer on its own. The shorter the wire, the less capacitance it will add to the circuit, so you should optimize the length of the wire wherever possible. If you want to stick with shielded wire, you should use a high-quality one with a low capacitance. I like to use the .155-diameter George L’s high-end wire for this. It’s very thin, with a capacitance of only 19 pF per foot, which is unbeatable ... but still affordable.
In comparison, I measured 46 pF per foot with the original wire from the factory. The before/after effect will be like lifting a blanket from the amp. But you can also use non-shielded wire if you’re not concerned about shielding. I replaced all wires in my 6120 with the George L’s .155-diameter cable and was able to reduce the original length of the wires to 50 percent, which means reducing additional capacitance to the circuit noticeably.
As you can see, tone is not set in stone, and there are ways to enhance your Gretsch wiring. Next month, we’ll dissect the Scott Henderson Stratocaster wiring, so stay tuned.

Montana’s own Evel Knievel
If artists aren’t allowed to take risks, and even fail, great art will never be made. Need proof? Check Picasso, Hendrix, Monk, and Led Zeppelin.
In sixth grade, I went to a strict Catholic school. When you have an Italian-Irish mother, that’s just part of the deal. The nuns had the look and temperament of the defensive line of the ’70s Oakland Raiders. Corporal punishment was harsh, swift, and plentiful–particularly toward boys—and we all feared them. All but one second grader. I can’t remember his first name; nobody used it, because his last name was Knievel. His uncle was Evel Knievel, the greatest and perhaps only celebrity ever to come from my home state, Montana. On the playground, we would watch in awe as this wild Knievel kid raced by us, nuns chasing in an awkward, sluggish pursuit as he knocked kids over, dust, books, and gravel flying behind his path of terror. This kid was fearless. It was truly inspiring to watch.
I hadn’t thought about my schoolmate for decades, until recently, when I saw Dave Chappelle talking about a terrible show he had in Detroit where the audience rebelled against him and began chanting, “We want our money back. We want our money back.” Chappelle told the angry mob: “Good people of Detroit. Hear me now. You are never getting your f*****g money back. I’m like Evel Knievel. I get paid for the attempt. I didn’t promise this shit would be good.”
Good art is a gamble. Look at Picasso. In 1907, he spent nearly a year drawing rough sketches and eventually painting his jagged, raw, unpretty Les Demoiselles d’Avignon. Picasso kept Les Demoiselles d’Avignon in his Montmartre, Paris, studio for years after its completion due to the mostly negative reaction of his immediate circle of friends and colleagues. After its first public showing in 1916, critics were hostile. Today, the painting is hailed as a pivotal moment in art history—the first true work of both Cubism and modern art. Many argue that the 20th century began culturally in 1907, with this painting that today hangs in the Museum of Modern Art in New York. Picasso wasn’t paid to make folks comfy; he got bank for shoving boundaries.
Similarly, I remember my sister and I watching a clip of Hendrix’s feedback-drenched “Star-Spangled Banner” at Woodstock. I couldn’t really process it at the time, but I knew I was watching something that had never been done. When he got to the “bombs bursting in air” part, it sounded like a barrage of explosions. Then, he references the mournful military bugle call “Taps,” played on bases at the end of each day and at funerals. My sister was offended. When I asked why, she said it was “unpatriotic.” I watch it now and I see a Black Army veteran who justifiably had a complex relationship with the country he had served. Martin Luther King was assassinated a year earlier, police brutality toward Black citizens was common. Black Americans were disproportionately stuck in low-wage jobs, and unemployment rates for Black workers were roughly double those of white workers. And although Hendrix was discharged, many of his Army buddies were overseas fighting a war they did not understand or support. So, yes, unpatriotic seems appropriate. But Hendrix’s performance was iconic because he dared to try to show his complex feelings through his guitar.“That’s the sweet spot: Fearless doesn’t mean flawless.”
Listen to Led Zeppelin’s groundbreaking “Black Dog.” The B section is so wonky, sticking out like a sore thumb with that weird timing that always feels wrong to me, but it would not be the rock masterpiece it is without that unsettling section. Maybe that’s the sweet spot: Fearless doesn’t mean flawless. Thelonious Monk’s janky genius proves that; those off-kilter notes hit you in the gut, not the head. Beck, Bowie, Coltrane… they didn’t polish away the edges; they leaned into them. That’s what makes you feel like a kid at an amusement park, wide-eyed and along for the ride.
When somebody hires me, they get what they get. I want to nail it, but art is subjective, so my idea of what feels right may not jibe with theirs. Humans are not great at communicating, so often I walk away from sessions and gigs wondering if my contribution was good, great, or garbage. But that’s a stupid question I try not to allow myself to indulge. You can’t do great work playing scared. There are times when music is not creative, just painting by numbers, trying to give the customer what they think they want. I do a lot of that to make a living, but that’s more like being a vending machine spitting out custom orders, not an artist.
Real artists are like that Knievel kid—leaving a trail of chaos, and not apologizing for it. I think artists who do it the best flip the script. Their audience isn’t just a judge, but a co-conspirator in the mess. They’re betting on the artist’s next move, not buying a finished product. They’re paying for the front-row seat to potential, not a flawless show. The paycheck was for the swing, not the home run. If the audience pays for “enjoyment” that turns artists into jukeboxes, not creators… if artists aren’t free to fail… innovation dies.

The Billy Idol guitarist rides his Knaggs into Nashville.
There’s nothing subtle about Billy Idol, so it tracks that there’d be nothing subtle about the guitars used onstage by his longtime guitarist, Steve Stevens. Famous for his guitar work with Idol and the Grammy-winning symphony of sustain “Top Gun Anthem,” Stevens brought a brigade of eye-popping signature electrics and some choice other jewels out on the road with Idol this spring.
The tour touched down at Bridgestone Arena in downtown Nashville in May, and while Stevens was jetting into town, PG’s John Bohlinger met up with tech and guitar builder Frank Falbo to learn the ins and outs of Stevens’ rig.

Cherry Pie
This cherryburst is one of a score of single-cut Knaggs Steve Stevens signature models in Stevens’ arsenal. He plays with heavier Tortex picks and uses Ernie Ball strings, usually .010–.048s.
More, More, More (Sustain)
This Knaggs Steve Stevens Severn XF, complete with a Sustainiac pickup system, was designed to mimic the look of one of his old guitars, and the stage lights make this finish go insane. It comes out for three to four songs in any given set, including “Rebel Yell.”
Songs from the Sparkle Lounge
This Knaggs Steve Stevens, finished in silver sparkle, is outfitted with a killswitch, push-pull control knobs, and Fishman Fluence pickups. Falbo was on the R&D team that helped design the Fluences.
Other guitars backstage include a red sparkle Knaggs with PAFs, a Godin LGXT with piezo saddles and Seymour Duncan pickups that sends three signals (synth, electric, and piezo), a pair of piezo- and MIDI-equipped Godin nylon-string guitars, a dazzling Gibson Les Paul with stock Gibson pickups, a Suhr T-style electric, and a Ciari Ascender for travel and dressing-room rehearsal.
Tube Heart, Digital Brains
Stevens runs through a pair of Friedman heads—a B100 and Steve Stevens SS100, plus a third backup—with each panned hard to either the left or right. Both signals run through a Neve 8803 rack EQ into two RedSeven Amplification Amp Central Evo loadboxes, and through their impulse response programs to front of house. A Neural Quad Cortex is on hand as a backup and for fly dates.
Steve Stevens’ Pedalboard
Stevens’ pedal playground is masterminded by an RJM Mastermind GT, which lives on its own board alongside a Fractal FM3 MK II. He orchestrates most of the changes himself, but Falbo is ready to flip switches backstage in case Stevens is away from his board for a key moment.
The centre hub, built on a Tone Merchants board, carries a TC Electronic PolyTune2 Noir, Xotic Effects Super Sweet Booster, Vox wah, Ernie Ball volume pedal, Mission Engineering expression pedal, DigiTech Whammy Ricochet, Suhr Discovery, JHS Muffuletta, DigiTech Drop, ISP DECI-MATE, Walrus Voyager, Suhr Koji Comp, Zvex Super Ringtone, DryBell Vibe Machine, and Ammoon EX EQ7. An Ebtech Hum Eliminator, two Strymon Ojais, and a Strymon Zuma keep the wheels greased.
The board to the right carries a Boss RV-500, Fender Smolder Acoustic OD, Lehle Dual Expression, Boss GM-800, Empress Bass Compressor, Grace Design ALiX preamp, Fishman Aura, and a Peterson tuner. Utility boxes include an Ernie Ball Volt and a Radial J48.
