Hey guys. Having a little problem with my amp, maybey, not sure whats the deal. So the other night at practice my cab starts sounding like its got a blown speaker, great. So I haul it down to the place I bought it, though did not bring my bass nor my amp. Played a J, through SWR amp to test it at the store and it sounded great. So what the hell. Checked my cables and I highly doubt its my amp. Can my P bass "clip" it self? What could make the distorted sound of a blown speaker if its not a blown speaker? I play an american P-bass, through a 400+ into a Mesa 410. Any ideas would be appreciated?
