DiMarzio P Bass Wiring Harness

The DiMarzio drop-in prewired P Bass wiring harness is engineered around custom 500K volume and 250K tone potentiometers designed specifically for high-impedance pickups. Featuring DiMarzio's proprietary custom taper, these potentiometers ensure smooth, precise control throughout their rotation. Each potentiometer is constructed with a solid machined brass center shaft and threaded bushing for maximum road reliability.
This preassembled wiring assembly streamlines bass upgrades with minimal soldering required. It comes complete with a Switchcraft output jack, heavy knurled metal knobs, and an Orange Drop .033 μF capacitor selected for a smooth, natural high-frequency roll-off.
Every harness is hand-assembled and tested in the USA utilizing lead-free silver solder and vintage-style 22-gauge push-back cloth wire. The pots fit standard 3/8-inch mounting holes commonly found on classic precision-style bass guitars.
