Have a Black, Neck through, late 80's to early 90's Washburn FOrce 40. Washburn does not have the wiring diagram for it. I have been enlisted to re-wire the thing after many a failed attempt. Help me please, it is a son of a gun!!! If nobody has one, a dual humbucker type system would probably work. It is not a P-bass or Jazz Bass style. It has 4 pot switches and a three way switch. If this at all looks familiar to yours, send me a diagram...please!!!
