Something is running hot in the electronics on my Gibson G3 bass. I've had 2 heads already cut out and start smoking before I realized maybe it was my bass doing this. I play sometimes on the E string and I notice when hitting some notes the volume level will fluctuate or sometimes make a farting noise. I was playing at band practice and the volume started cutting out and I smelled something funky from the head so I immediately turned it off. I plugged in another bass to the head and everything worked fine so I believe it's my bass. Any idea what's going on?
