I have played bass for a long time but am an electronics noob. I have read through the stickies on electronics but don't want to waste time or money because I misunderstood. I have an old bass that I want to refurb and learn a few things on. My question: The pickups are a G&L l1000 pickup and a jazz pickup labelled Bartolini. Both date from the early to mid 80's. Right now everything is passive. I think I can use any preamp with these pickups (Sadowsky, Aguilar, Audere, East, Carvin). Am I correct? Any suggestions on what might work well? The body is an L1000 that was routed for the J pickup in the bridge position. Thanks for your advice.
