Hi everyone, I have a Schecter Stilletto Studio fretless 5 that has had all the electronics (except the pickups) replaced by Schecter. The noise has changed from a whiny squeal to a hiss which is to audible to play with the treble EQ knob any higher than 1/4. Of course as hard as they tried, Schecter could not hear the noise. At this point I'm thinking of making this bass passive. It has EMG Hz40 pickups. Any thoughts ? Thanks, TC
