ok, so I started a thread a while bak about an amp i was renting, a 400+ that seems to start distorting badly at a medium volume http://www.talkbass.com/forum/showthread.php?t=222740 The concensus was that the amp was bad, most likely a tube problem. I just bought a 400+ from a TBer, and guess what - SAME PROBLEM. So, I have the vol1 (the preamp) on maybe 7 so it's not distorting, and if I turn up the master past 3 or so, it's breaking up like crazy. It's not SUPER loud either. I couldn't get enough clean volume for my show last night at a medium (100 people) bar. (i'll post some gig pix shortly!) I played through an eden 410xlt (700w) I also played my other amp that distorted through my ampeg 410hlf... so I know the cabinet isn't bad (unless for some crazy reason they are both bad, which i doubt very much) If I get a chance, I'll post some audio from he show, but it's distorted like crazy, trust me. Any ideas here? I'm stumped. BOTH amps are no good? Could it be that the cabs i'm using simply can't handle the volume & it's the cabs that are crapping out? any easy way to tell? Or could it be that I expect too much from a 400+ clean-volume-wise? help.... !
