hey! this may be in the wrong forum but sure anyway..... I don't know what a preamp is! is a preamp the volume and tone(eq) knobs on a bass? I'm just guessing here maybe it counts as the pickups or maybe its the pickups and the volume and eq knobs?!?!?! also does a preamp VU monitor not work if you do not have an active bass any help would be much appreciated- cheers!
