Im skeptical about the tubes in it now, it has 2 fender 6l6GC's and 3 12ax7 groove preamp tubes, which i imagine are over 6 or 7 years old. could it be the old tubes causing the poor distortion sound quality? Sure could be, leave it in for service if you belive it's the bad egg so they can check it up for you. -------------------- My bands homepage

thanks for the suggestions guys, I would order the JJ tubes but i already have a set of Ruby tubes on order, but ill keep the JJ's in mind next time i wanna try some new tubes. I just really hope these new tubes clean up the distortion. If you don't know already - Be VERY CAREFUL if you open your amp to do it yourself. Drain it before you start working on it or you might get a 700-Volts-through-yout-body kind of surprise. -------------------- My bands homepage

Well installed the new tubes today, taking the precautions you guys suggested and they installed with no issues. the ruby preamp tubes i installed are actually JJ tubes. I was suprized to see the JJ label on them when I popped them out of their little boxes. The old tubes were def. dead and the new tubes sound alot better, however the distortion channel still sucks. I think its just this particular amps distortion circuit that sucks. Any more ideas on how to clean up the distortion channel any? Yeah, bring it in for service. They might offer a couple of new tubes for a matching set. I never work on my own amp, tubes have to be matched and biased. And when you buy a few from the store there's little chanse they will be matching. And after you plug em in to your amp they should be biased for best output, if the bias is off you got tubes that either don't run on their full potential or they run too hot. -------------------- My bands homepage
