J-Bass Wiring Harness- Copper Foil

These aren’t your average bargain-bin electronics with cold solder joints and scratchy signals. Every CLE GUITAR WORKS harness is hand-built and road-tested using only premium components — because your tone deserves better, and cheap parts have no place between your pickups and your amp.

Each harness includes:

★ CTS POTENTIOMETERS for smooth, consistent control

★ SWITCHCRAFT SWITCHES and DUAL-CONTACT JACKS for rock-solid reliability

★ Hand-wired by yours truly — with over 20 YEARS of experience wiring and modding guitars for A-LIST ARTISTS around the world

★ Vintage-spec push-back wire

★ Or Pure 20 AWG 5N SILVER lead wire (Depending on the series), paired with 16 AWG ground bus wire — delivering a clean, stable, and transparent signal chain.

Also included:

★ JUPITER CONDENSER CO. CAPACITORS — premium, American-made caps trusted by even the most tone-obsessed audiophiles. They deliver the clarity and musicality your rig deserves, both in the STUDIO and ON STAGE.

Wiring is the unsung hero of your signal chain. It’s not flashy — but it’s the main artery that carries your tone from pickup to amp:

UNCOLORED. UNFILTERED. EXACTLY how it’s meant to sound.

DON’T LET WEAK PARTS CHOKE YOUR SIGNAL.

DON’T LET CHEAP WIRING FAIL YOU ON STAGE.

INVEST IN RELIABILITY. INVEST IN TONE.

★ Compatibility

Fits most USA Fender Jazz Bass models with standard control plates.

Also compatible with most Squier Jazz Bass models; however, factory components (typically Alpha-brand pots) use smaller metric-sized shafts and mounting holes, so careful reaming may be required to fit ⅜” CTS pots.

This harness is wired in the typical Precision Bass configuration — one master volume and one master tone.
