Made it out of a cheap Dean bass some years ago. I was inspired by the Warwick explorer and buzzard basses, and it would be perfect except for the clear coat I applied cracked everywhere and as others have said the E A and D G strings are like two different instruments. The neck PU is in the standard P location and each one sounds great on its own, but together it just doesnt work.
Going to try two EMG 35 P pickups in my Spector 4 string next to see how that works.
