Got myself a real beast of a bass, couldn't be happier... When it works. Occasionally (much more often lately) the sound will crackle, which sounds just like when you wiggle around oxidized pots, and then fades into silence all without me touching anything except playing the strings. I think I narrowed it down to something battery related, because when I messed with the battery (changing it out, moving it around) some of the same crackling happens again. Most curiously, the only reliable way to fix it (temporarily) is to unplug the jack and plug it back in. This causes a lot more interference than I would expect, but immediately after I plug it in the bass sounds just like normal, until it decides to do its thing again. This sound familiar to any of you guys?
