All the punch of a classic Precision Bass — plus a whole new tonal voice on demand. The Sonic Pickups P Bass Dual Tone Pre-Wired Harness adds a push/pull tone pot that switches between two capacitor values, giving you the vintage P Bass tone you know and a richer, warmer option when you need it.

The Dual Tone Feature
Tone pot down: Standard .047µF cap — the classic P Bass tone rolloff used for decades. Tone pot pulled up: .1µF cap engaged — a deeper, warmer cut that opens up a whole new tonal palette without touching your pickups or amp.
Compatibility
Fits standard Precision Bass body routes. Designed for USA-spec pot holes (3/8"). Basses manufactured outside the US may require drilling pot holes to 3/8" to fit. 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 pickup and output jack — most players complete the install in under 30 minutes. Includes a wiring diagram.
