21 Classic & Modern Tones

From JP–style experimentation to modern gigging flexibility:

• Full humbuckers

• Coil-split single-coils (both pickups)

• Out-of-phase tones for cutting, nasal character

• Fat, powerful series wiring

• Clean blending in middle position (no signal cut at “0”)

• Push-push pots for fast switching on stage

Requirements & Compatibility

To ensure a smooth installation and full functionality, please review the following fit and wiring requirements:

• Potentiometer Mounting Holes:
  Requires ⅜" (9.5mm) diameter holes to fit the low-profile push-push pots.
  Most import guitars will need to enlarge their holes slightly using a hand reamer (not a drill) for a clean fit.

• Body Style:
  Designed for Les Paul–style guitars with a standard 2-volume / 2-tone / 3-way toggle control layout. Works with most Gibson Les Paul, Epiphone Les Paul, PRS SE Single Cut (2v - 2T), Harley Benton, kit builds, Chibsons, and custom LP-style guitars.

• Knob Fitment:
  Pots are fine-spline U.S.-sized shafts (24-tooth).
  Use U.S.-spec knobs only. Import knobs may not fit.

• Pickup Wiring:
  Requires 4-conductor pickup wiring with a separate bare ground wire for full solderless installation. Pickups with vintage braided wire are supported, but will require soldering the ground to the terminal block.

• Toggle Switch Wiring:
  Compatible with toggle switches wired with 4-conductor (shielded) cable.
  For best results and easiest solderless installation, we recommend the Calitone 4-Conductor Shielded Switch, which is selectable as an option.

💬 F.A.Q.

Q: Why do the volume knobs not go completely silent at zero?
A: To preserve blending in the middle position—just like Page’s rig. Series mode acts like a kill switch when in the bridge position.

Q: Is this 50s wiring?
A: No. We use 60s-style wiring for smoother volume response and blendability.

Q: Do the push-push pots work like push-pull pots?
A: Yes, but push-push pots are faster and easier to switch, especially live—no need to pull the knob up.

Q: Will this fit my Epiphone or import LP?
A: Yes—as long as it follows the Les Paul 2V/2T layout and control holes are widened to ⅜" (9.5mm). Perfect for kits and modders.

Q: What type of pickup wiring is required?
A: This harness is designed for pickups with 4-conductor wiring and a separate bare ground wire.
