Hey all, The group I play with has moved to a new practice venue. It is an office space that is part of a commercial complex. Here is my issue: when I play my FBass in this venue, I get a loud hum that changes as my bass moves through the environment, e.g. if I aim the neck down, the hum reduces, as I change direction the hum changes. Nothing makes it stop. Note: when I play my Sadowsky in the same venue on the same amp with the same cables...no hum at all. Second note: when I play the FBass at home or any other venue (to date)...no hum at all. I generally play my FBass through a Zoom B3 (for reverb)...I tried lifting ground on both the amp and the pedal (together an individually). Still humming. I removed the pedal and went direct to the amp. Still humming. Is this a byproduct of less than perfect wiring in the practice environment? I don't understand why it only affects one bass and not the other. Is this poor shielding on the FBass? Then why does it only happen in this room? Any suggestions? As of now I just don't rehearse with my FBass, but it would be nice if I could solve this so it would be an option. Thanks!
