Ok, recently I bought a Jazz bass from a fellow TB'r. Warmoth jazz body and old MIJ fender neck.Dual EBMM style bartolini pups and active/passive bart pre amp(dont know the model). First off I LOVE THIS BASS!! The tone is just awsome. But the output seems just way to low. I raised the pups which helped a little. I replaced the battery in the pre. But when I plug it in I have to turn my SVT II up to 5!!!! To get it to match the output of my other basses. I want to run this bass passive. It just sounds so much more "classic" tone wise. Active gives it a bit more volume but robs the tone quality a little IMO. Its got no poop?? I like this bass enough to gut it and get new pups and or pre if need be. Either some kind of duncan or EBMM stock pups. I dunno what else is available thats really good in the EBMM pup shape. As I said I want to run this bass passive. Tubes in my amp are fine. Theres no rig issues. Anyone have any thoughts?
