Hi, everyone. I tried searching for something like this but I didn't find anything. I recently got a used Fender Jazz that came with Bartolini pickups, I don't know which. The bass seems to have had a preamp in it before (taken out before I bought it) -- the control plate and knobs have been replaced and there's an extra output jack that had been drilled into the side of the body that I'm going to fill in. The bass itself is very quiet, quieter than any jazz I've played before. Has Bartolini ever made pickups that are designed to go along with an onboard preamp? Thanks a lot for any help, guys.
