My bass teacher has an early 1980s Fullerton Jazz with stack knobs. What kind of pickups/ electronics are in one of these? It has a very gutsy tone (it's so hard to talk about this and make any sense.) All I know is that it plays amazing and sounds incredible. I have a 60s reissue Jazz that I really like and I'm getting to play very smoothly with steel wool. How can I get my bass to start approaching the sound his gets? Thanks!
