Leftys all know that Fender uses right handed pots in left handed guitars resulting in horrible taper and non-intuitive function.
This drop in harness uses correct left handed audio taper pots to solve that problem.
This will drop right in your lefty P Bass pickguard and restore what should have been the correct function in the 1st place.
Hook up your pickup ground to the loop that I double soldered on the back of the volume pot and your pickup hot to the volume lug and you are almost done. I've also included a plain tinned ground wire for patching in the bridge ground and an additional ground that you can trim to length and use the included lug to replace the cavity ground (if your bass uses one).
 2 x 250K left hand taper Bourns audio pots with 6mm solid shafts and adapter sleeves so they fit US spec 1/4" knobs
.1uf New Old Stock USA Made Micamold 100v Paper In Oil capacitor
Switchcraft #11 output jack
Ground lug for cavity ground

I can make this harness with a variety of capacitor types and values. Send me a message and let me know what you need.
