My Engelhardt EM-1 is equipped with a K&K Bass Max. It's the only pickup I've ever used. My signal goes through a Headway EDB-1 preamp to a Genz Benz 6.0. I'm currently working with a trio Female vocal/guitar, drums, URB. Low to moderate volume. Mostly acoustic with some electric guitar. I'm thinking of switching to Gage Realist. Anyone care to chime in with observations or advice.
