With out-of-phase and coil-switching options, a treble-bleed network, and individual volume and tone controls for each pickup, this dual-humbucker’s wiring was ahead of its time when it came out in 1978.
Recently a customer asked me to translate something for him, and it turned out that it was a German description of an electric guitar that I had almost forgotten about: the Peavey T-60.
I must admit that I really like Peavey guitars, and the T-60 is no exception. The guitar and its wiring are so unique that I wanted to show you the circuit and how you can adopt it for your own guitar.
The Peavey T-60 was built from 1978 to 1988 and is a dual-humbucker guitar with a design that was ahead of its time—kind of "Burns meets Stratocaster." It's a polarizing shape: You will either love it or hate it. Personally, I think it's a spacey design and together with the arrow-shaped headstock, the silver retro control knobs with the inlayed "P" for Peavey, the toaster-style pickup covers, and the countless screws holding the pickguard, it looks super cool ... but judge yourself.
The guitar was loaded with two epoxy-potted four-conductor "full-range" humbuckers with a blade design, aka Super Ferrite pickups. They were covered with Rick-style toaster design pickup covers, had standard PAF dimensions, and were designed to sound good as humbuckers and single-coils when in split mode. The T-60 guitar also had a brother: the T-40 bass, with the same wiring but slightly different capacitor values for the treble-bleed network on the volume pots (more on this later).
I haven't seen such a circuit on any other guitar. You can adopt this wiring to any HH guitar as long as both humbuckers have four-conductor wiring and a Les Paul/SG/335-style control layout.
The wiring was really ahead of its time back in 1978, sporting out-of-phase and coil-split options, but in a very special way. Basically, the original wiring is using a 3-way pickup selector switch (in this case a DPDT on-on-on type) for a Les Paul-style switching with both pickups together in parallel in the middle position. Next there is a DPDT on-on switch, serving as an out-of-phase switch for the bridge pickup, and a 250k volume and tone control for each pickup, á la Les Paul but independent from the other pickup's circuit. The volume controls both have a "cap only" treble-bleed network to keep the high-end alive when rolling down the volume. The value for the T-60 guitar was 1000 pF and for the T-40 bass 0.01 uF. Besides this, the wirings are absolutely the same. The tone controls have a 0.033 uF tone cap for the bridge and a 0.022 uF tone cap for the neck pickup.
So far, this is nothing special in the year 2020, but let's take a closer look at the tone controls. Here we find a mixture of a tone blend and a coil blend feature. On one side a capacitor is blended to ground (tone blend) while on the other side one of the coils is blended to ground (coil blend). Since the out-of-phase switch is still in front of the coil blend feature, you can choose, depending on the position of the switch, which of the two coils is blended to ground. Here is the description of the circuit in Peavey's own words from the original manual of the guitar: "Our unique tone circuitry enables dual- or single-coil operation of each pickup independently through the rotation of the pickup tone controls. Rotating the tone controls fully clockwise (position #10) achieves the single-coil mode and produces a greater degree of "highs" from the instrument. Rotating the tone controls counterclockwise to approximately the #7 position brings the second coil into operation for full-range, humbucking tonalities. Further counterclockwise rotation of the tone controls (from position #7 to 0) yield conventional tone-contouring action."

As always, the out-of-phase switch only works when both pickups are engaged. Different from a Les Paul standard wiring, both volume and tone controls are working independent from the other pickup's circuit, so in the middle position with both pickups engaged in parallel, the volume and tone controls only affect their corresponding pickup and not both, interacting with each other.
All this together creates a very flexible circuit with a lot of tonal shades you can dial in. I haven't seen such a circuit on any other guitar. You can adopt this wiring to any HH guitar as long as both humbuckers have four-conductor wiring and a Les Paul/SG/335-style control layout. Before you dive in, here are some points to consider with this wiring and possible mods of this circuit:
- Peavey chooses a "cap only" 1000 pF treble-bleed network for both volume controls. This will work with the original 250k controls and the special humbuckers, but may be adjusted when using other humbuckers and/or values for the controls. For more info about this, please have a look at my March 2019 Mod Garage column "Deep Diving into Treble-Bleed Networks."
- The original wiring uses a 0.033 uF tone cap for the bridge and a 0.022 uF tone cap for the neck pickup. Naturally you can mod these values to your personal likings, e.g. 0.022 uF for the bridge and 0.01 uF for the neck pickup, which will work fine with any vintage PAF-style humbucker. Or maybe you want to convert to a warmth control, which is described in November 2018's "Mod Garage: Swap that Tone Knob for a Warmth Control."
- The Rick-style toaster covers on the original humbuckers may look cool, but will dampen the high-end noticeably because, unlike the similar-looking covers from Gretsch, the metal between the two slits is uninterrupted. Removing the cover will bring back all the high-end. Alternatively, you can cut a piece out of this metal part, so it looks similar to the Gretsch covers, to solve the problem and retain the cool retro appearance. (Remember: breaking eddy currents!) For more info about this, read "Mod Garage: How to Shield Humbucking Pickup Covers" from January 2019. For the original pickups, Peavey recommends a pickup height adjustment of 1/32" (0.8 mm) for the bridge and 3/64" (1.2 mm) for the neck pickup. If you want to use the original pickups, chances are good that you'll find a used pair on eBay or maybe Peavey still has them in stock. The part number for the pickups is 95201100 (one model for bridge and neck).

- Peavey used 250k audio pots for the volume and 250k tone pots offering a special "S" curved taper. I'm pretty sure this was owed to the S-taper and the availability of such pots, because usually you would expect a 500k pot here together with humbuckers. Not the best choice, so it's worth using all 500k audio pots or a combination of 250k audio pots for the volume (60:40 audio taper in preference) and 500k for the tone controls, preferably with an S-taper. Standard audio-tapered pots will also work with this wiring, but the crossover point between tone blend and coil blend is more defined with an S-curved taper. Such S-tapered pots are available from Bourns or CTS. Maybe the original 250k pot is still available from Peavey as a spare part: the part number of this pot is 75065005.
Now let's look at the wiring. For visual clarity, we'll start with the volume pot's treble-bleed network shown in Fig 1. It's a single 1000 pF cap soldered between input and output of both volume pots. Silver mica caps do a very great job here.
The entire complex wiring of the Peavey T-60 is shown in Fig. 2. The wiring is shown with the original Peavey pickup color chart and needs to be transferred when using different pickups. You can use a lot of different online resources for this, such as the one on guitarelectronics.com.
That's it. Next month we'll continue with our relic'ing series (catch up now with part 1 and part 2) take care of the metal parts of the tuners. Until then, keep on modding!

“Practice Loud”! How Duane Denison Preps for a New Jesus Lizard Record
After 26 years, the seminal noisy rockers return to the studio to create Rack, a master class of pummeling, machine-like grooves, raving vocals, and knotty, dissonant, and incisive guitar mayhem.
The last time the Jesus Lizard released an album, the world was different. The year was 1998: Most people counted themselves lucky to have a cell phone, Seinfeld finished its final season, Total Request Live was just hitting MTV, and among the year’s No. 1 albums were Dave Matthews Band’s Before These Crowded Streets, Beastie Boys’ Hello Nasty, The Miseducation of Lauryn Hill, Korn’s Follow the Leader, and the Armageddonsoundtrack. These were the early days of mp3 culture—Napster didn’t come along until 1999—so if you wanted to hear those albums, you’d have to go to the store and buy a copy.
The Jesus Lizard’s sixth album, Blue, served as the band’s final statement from the frontlines of noisy rock for the next 26 years. By the time of their dissolution in 1999, they’d earned a reputation for extreme performances chock full of hard-hitting, machine-like grooves delivered by bassist David Wm. Sims and, at their conclusion, drummer Mac McNeilly, at times aided and at other times punctured by the frontline of guitarist Duane Denison’s incisive, dissonant riffing, and presided over by the cantankerous howl of vocalist David Yow. In the years since, performative, thrilling bands such as Pissed Jeans, METZ, and Idles have built upon the Lizard’s musical foundation.
Denison has kept himself plenty busy over the last couple decades, forming the avant-rock supergroup Tomahawk—with vocalist Mike Patton, bassist Trevor Dunn (both from Mr. Bungle), and drummer John Stanier of Helmet—and alongside various other projects including Th’ Legendary Shack Shakers and Hank Williams III. The Jesus Lizard eventually reunited, but until now have only celebrated their catalog, never releasing new jams.

Back in 2018, Denison, hanging in a hotel room with Yow, played a riff on his unplugged electric guitar that caught the singer’s ear. That song, called “West Side,” will remain unreleased for now, but Denison explains: “He said, ‘Wow, that’s really good. What is that?’ And I said, ‘It’s just some new thing. Why don’t we do an album?’” From those unassuming beginnings, the Jesus Lizard’s creative juices started flowing.
So, how does a band—especially one who so indelibly captured the ineffable energy of live rock performance—prepare to get a new record together 26 years after their last? Back in their earlier days, the members all lived together in a band house, collectively tending to the creative fire when inspiration struck. All these years later, they reside in different cities, so their process requires sending files back and forth and only meeting up for occasional demo sessions over the course of “three or four years.”
“When the time comes to get more in performance mode, I have a practice space. I go there by myself and crank it up. I turn that amp up and turn the metronome up and play loud.” —Duane Denison
the Jesus Lizard "Alexis Feels Sick"
Distance creates an obstacle to striking while the proverbial iron is hot, but Denison has a method to keep things energized: “Practice loud.” The guitarist professes the importance of practice, in general, and especially with a metronome. “We keep very detailed records of what the beats per minute of these songs are,” he explains. “To me, the way to do it is to run it to a Bluetooth speaker and crank it, and then crank your amp. I play a little at home, but when the time comes to get more in performance mode, I have a practice space. I go there by myself and crank it up. I turn that amp up and turn the metronome up and play loud.”
It’s a proven solution. On Rack—recorded at Patrick Carney’s Audio Eagle studio with producer Paul Allen—the band sound as vigorous as ever, proving they’ve not only remained in step with their younger selves, but they may have surpassed it with faders cranked. “Duane’s approach, both as a guitarist and writer, has an angular and menacing fingerprint that is his own unique style,” explains Allen. “The conviction in his playing that he is known for from his recordings in the ’80s and ’90s is still 100-percent intact and still driving full throttle today.”
“I try to be really, really precise,” he says. “I think we all do when it comes to the basic tracks, especially the rhythm parts. The band has always been this machine-like thing.” Together, they build a tension with Yow’s careening voice. “The vocals tend to be all over the place—in and out of tune, in and out of time,” he points out. “You’ve got this very free thing moving around in the foreground, and then you’ve got this very precise, detailed band playing behind it. That’s why it works.”
Before Rack, the Jesus Lizard hadn’t released a new record since 1998’s Blue.
Denison’s guitar also serves as the foreground foil to Yow’s unhinged raving, as on “Alexis Feels Sick,” where they form a demented harmony, or on the midnight creep of “What If,” where his vibrato-laden melodies bolster the singer’s unsettled, maniacal display. As precise as his riffs might be, his playing doesn’t stay strictly on the grid. On the slow, skulking “Armistice Day,” his percussive chording goes off the rails, giving way to a solo that slices that groove like a chef’s knife through warm butter as he reorganizes rock ’n’ roll histrionics into his own cut-up vocabulary.
“During recording sessions, his first solo takes are usually what we decide to keep,” explains Allen. “Listen to Duane’s guitar solos on Jack White’s ‘Morning, Noon, and Night,’ Tomahawk’s ‘Fatback,’ and ‘Grind’ off Rack. There’s a common ‘contained chaos’ thread among them that sounds like a harmonic Rubik’s cube that could only be solved by Duane.”
“Duane’s approach, both as a guitarist and writer, has an angular and menacing fingerprint that is his own unique style.” —Rack producer Paul Allen
To encapsulate just the right amount of intensity, “I don’t over practice everything,” the guitarist says. Instead, once he’s created a part, “I set it aside and don’t wear it out.” On Rack, it’s obvious not a single kilowatt of musical energy was lost in the rehearsal process.
Denison issues his noisy masterclass with assertive, overdriven tones supporting his dissonant voicings like barbed wire on top of an electric fence. The occasional application of slapback delay adds a threatening aura to his exacting riffage. His tones were just as carefully crafted as the parts he plays, and he relied mostly on his signature Electrical Guitar Company Chessie for the sessions, though a Fender Uptown Strat also appears, as well as a Taylor T5Z, which he chose for its “cleaner, hyper-articulated sound” on “Swan the Dog.” Though he’s been spotted at recent Jesus Lizard shows with a brand-new Powers Electric—he points out he played a demo model and says, “I just couldn’t let go of it,” so he ordered his own—that wasn’t until tracking was complete.

He ran through various amps—Marshalls, a Fender Bassman, two Fender Super-Sonic combos, and a Hiwatt Little J—at Audio Eagle. Live, if he’s not on backline gear, you’ll catch him mostly using 60-watt Blackstar HT Stage 60s loaded with Celestion Neo Creambacks. And while some boxes were stomped, he got most of his effects from a Line 6 Helix. “All of those sounds [in the Helix] are modeled on analog sounds, and you can tweak them endlessly,” he explains. “It’s just so practical and easy.”
The tools have only changed slightly since the band’s earlier days, when he favored Travis Beans and Hiwatts. Though he’s started to prefer higher gain sounds, Allen points out that “his guitar sound has always had teeth with a slightly bright sheen, and still does.”
“Honestly, I don’t think my tone has changed much over the past 30-something years,” Denison says. “I tend to favor a brighter, sharper sound with articulation. Someone sent me a video I had never seen of myself playing in the ’80s. I had a band called Cargo Cult in Austin, Texas. What struck me about it is it didn’t sound terribly different than what I sound like right now as far as the guitar sound and the approach. I don’t know what that tells you—I’m consistent?”

The Australian-American country music icon has been around the world with his music. What still excites him about the guitar?
Keith Urban has spent decades traveling the world and topping global country-music charts, and on this episode of Wong Notes, the country-guitar hero tells host Cory Wong how he conquered the world—and what keeps him chasing new sounds on his 6-string via a new record, High, which releases on September 20.
Urban came up as guitarist and singer at the same time, and he details how his playing and singing have always worked as a duet in service of the song: “When I stop singing, [my guitar] wants to say something, and he says it in a different way.” Those traits served him well when he made his move into the American music industry, a story that begins in part with a fateful meeting with a 6-string banjo in a Nashville music store in 1995.
It’s a different world for working musicians now, and Urban weighs in on the state of radio, social media, and podcasts for modern guitarists, but he still believes in word-of-mouth over the algorithm when it comes to discovering exciting new players.
And in case you didn’t know, Keith Urban is a total gearhead. He shares his essential budget stomps and admits he’s a pedal hound, chasing new sounds week in and week out, but what role does new gear play in his routine? Urban puts it simply: “I’m not chasing tone, I’m pursuing inspiration.”
