Two wiring modes, one pull of a knob — and it fits where standard pots won't. The Sonic Pickups J Bass Mini Pot Series/Parallel Pre-Wired Harness lets you switch your Jazz Bass pickups between standard parallel wiring and a thick, powerful series mode, all in a compact form factor built for non-USA-spec routing.

Series vs. Parallel
Parallel (pot down): Standard Jazz Bass tone — clear, articulate, and balanced.
Series (pot up): Both pickups wired in series — louder, thicker, and more mid-forward with a P Bass-like punch.
Who It's For
Basses made outside the US are often routed for smaller pots. This harness solves that — premium parts and expanded switching, no routing required.
Compatibility
Designed for Jazz Bass-style instruments with non-USA-spec pot cavities. Works with standard USA-sized knobs. Select your output jack preference and include your bass's make, model, country of manufacture, and handedness in your order notes so we can confirm fit before shipping.
Drop-In Installation
No point-to-point soldering required. Simply connect your pickups and output jack — most players complete the install in under 30 minutes. View Wiring Diagram.
