Hello all: This is really strange. Sometimes my bass goes "dead", and the only way to bring it back is to turn the balance knob back and forth. As I do this, it will cut in/out, and finally will be ok. What's even stranger is I've noticed if I get a small static shock while holding the bass (I practice on a carpet, and sometimes when I stand my calf touches the metal leg of my chair, giving me a tiny static shock), the bass instantly cuts out. My electronics are: Dimarzio Ultra Jazz pups EMG BTC preamp Controls are Volume, balance, stacked bass/treble. The Vol is a push-pull to bypass the preamp. The problem happens in either active or passive mode, but seems more frequent in active mode. Any ideas?
