I'm using a customized (thanks to Bob Gollihur, who prevailed upon the factory) K&K and an AI Contra. No mic. I sat in with a guitar-vocalist duo for two sets. The first set, I was setting up as they were working, couldn't connect cables, etc., and Vic said "Leave it off, I hate amps," so I did the set acoustically. Second set, I played amped. At the end, they saw the light on and asked "Was that turned on? All I heard was the bass." That's the way it's supposed to be, right? Thanks K&K; thanks, AI; thanks, Bob. I've used Polytone, Fishman, Barbera, Ampeg (tube), and G-K; never got a sound like this before.
