I have a warmoth jazz with Dimarzio ultra jazz (5 string pups) and an aguilar OBP-3. The output is on the low side (meaning my passive stock American Jazz is a decent amount louder than this bass). Will pot value play a large role in output? I have 250 ks wired up as I had them sitting around, but plan on rewiring with 500 when I refinish the bass and add series/parrallel switching and possible a passive tone. Also, does anyone know if the aguilar has an adjustable gain anywhere or way?
