1982 Peavey T 60 - CLOSET QUEEN!

[@JobyP]

Ohhhhh Myyyy Gooooddddd lol! This thing is RAD! Here is what is actually going on with the wiring from a premiere guitar article. 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."

OMG that's amazing

I didn't know that Peavey made guitars. That is definitely RAD! Hope you're doing well, Joby! 🎸

[@JobyP]

They are American Made and the are super rad bud!!! Found well hope the same is true for you brother!

This was my first guitar in ‘78, And now I have 3 of them. Two I customized with a third blade pickup. So, the phase switch is now the coil tap and the Nashville sounds come from the middle pickup like a strat.

That’s awesome! I did end up buying the guitar from my friend BTW 😀

[@markhammer643]

I wired up an old Vantage project guitar with the T-60 tone control on the bridge pickup, as well as a phase switch for that pickup. As you're likely aware, the T-60 tone control circuit pans from one coil of an HB, through to both coils with no treble cut, to both coils *with* treble cut, providing coil-cancel (what some refer to as coil-split) without the need for an additional switch. On my guitar, though, the phase switch ends up changing *which* of the two coils is heard, when the Tone knob is in the "bright" position. Much to my surprise and amazement, the two coils sound very different from each other, largely because of their relative distance from the bridge. A very clever circuit. Thanks, Mr. Lorento!

It really is neat and I can’t understand why more guitars haven’t utilized this. To my ears it destroys the sound of a coil tap/split thanks for watching/commenting it’s appreciated cheers 🍻

@@JobyP I don't know if it 'destroys' coil-cancellation,, but it does provide a lot more variety for very little in parts and effort. On that same Vantage guitar, I also implemented the Bill Lawrence '"half out of phase' mod. By cutting bass content of the neck pickup with a series capacitor, putting neck and bridge out of phase does NOT result in that thin annoying tone with the big volume drop. On Telecasters, it yields a tone strikingly like neck+middle on a Strat, despite having no middle pickup, and with NO volume drop. It obviously won't sound very Strat-like on a dual-humbucker guitar, but it does yield another very usable N+B tone.

@@markhammer643 That’s awesome I just love the implementation so much better than other coil taps I’ve tried. And used in my own instruments I’ve built. It’s a great circut.

@@markhammer643 P.S. sorry for the slow reply KZbin seems to never alert me to replies… only the original comment so I check them sporadically

[@rjbrando9616]

From 10-7 on the tone the pickup is in single coil, from 7-1 it acts like a standard tone but the pickup is in humbucker mode

[@rjbrando9616]

The phase switch changes the bridge pickups active single coil. The trick is to roll of one pickups volume to bring back the fullness and avoid the thin sound.

[@JobyP]

Yeah I figured it out... sooooooooo cool! P.S. the guitar ended up staying with me :) Cheers and Thanks!
