I have been looking into buying a preamp lately, because my bass is Passive, and I like the sound of an active, but not all the time. I have been looking at the Sadowsky foot preamp that has a bypass switch which I think would be very nice. I love the tone of a passive, but sometimes want that bass and treble boost that an active can supply. Also if anyone knows another good Preamp company besides Sadowsky, I would like to know what they are. None of the big amp companies make preamps.
