Hi. I just bought a 5-string Salas bass from bassalone.com. (See my thread under basses if you're interested). The bass has a Duncan STC-3A preamp in it (18 volt). I've never owned or played bass w/a Duncan preamp before, and am having trouble judging the preamp's effect on my bass, because the bass itself is unique. So I'm askin'. . . what are people's experiences with Duncan preamps?
