Okay, for pretty much most of the last week or so I have owned my new (used) Streamer STD (not Rockbass), I have been playing at verrry low volume thru a small practice amp. Tonite I cranked it up a bit thru the only big amp I have, a Peavey Kb/A 300. The problem? Best explained this way... If I hit a (primarily) low note, and let it sustain, after a little time it starts to "fuzz" like the speaker is blown, and then the volume drops by about 1/2. I tried my other bass (ATK300 active) on the same amp with no similar effect. Leads me to think I have either a bad pot, or resistor, or something. Any suggestions? I can wire your house like a pro electrician, but at electronics I am a numb-skull. BUT, I can solder well! Help anyone?
