okay, so I have had this little crate bx-15 practice amp for about 3 years and its been pretty faithful...but the last bass I had was a gibson g-4 grabber and this little amp would always give it terrible static and sometimes not even pick up the notes at all. now, i got a brand new fender jazz bass and i am having the same problem. i am playing on a new cord that i bought thinking that would solve the problem...the amp now after playing yesterday for some reason wont even register at all. i cant hear anything besides the occasional static. is the amp just done or, what? the only reason a little 15 watter concerns me is cause its nice to practice and play outside and be mobile with it. anyone know anything?
