Just finished my latest build today, and proudly brought it to practice. So I play the thing in for the first time and she sounds great, until I try to hit the overdrive pedal and signal cuts. Turn the pedal off, bass comes back on. I try different pedal, and it also cuts the sound. No mute buttons or anything like that has been hit. All cables are working, pedals work fine with other basses and guitars. Why won't it play with my new bass? Electronics are a set of active EMG JV's.
