im trying to upgrade a bass i purchased the other day, its not the first time i have done this, but it is the first time i have tryed to turn a passive into an active bass... the bass is an early 2000s squier jazz bass, it does not have the control plate or pickguard so i plan to widen the cavity and make room for active electronics for the build. not to install a drop in plate preamp. i have been looking around at different preamp ideas, and i have decided on installing the audere 3ZB. now my concern is what pickups to choose? im not exactly sure how having an onboard preamp functions with passive or active pickups i havnt experienced much with it before. so im wonder what would be some good suggestions for jazz style pickups that would work well with the audere?? Active or Passive?? and has anyone ever installed a dual battery box with an audere preamp to save room in the cavity?? and where would be a good location on a squier jazz bass for a battery box?? i would like to go that route to make it easier for changing batterys. any suggestions or input is appreciated.
