Today at rehearsal the guys asked me if I had a button on my sleeve because I was sending a clicking noise through the PA when I played. Never did quite nail down what was going on but it seems like it was coming from either the frets when I pushed them down with my left hand or when I plucked the strings with my right hand. Seems to occur only when I'm into it and playing hard. Have a Musicman Slow Special so I can't blame the bass. Anyone else ever have this issue and can suggest ways to circumvent it. Thanks.
