    I'm having an amp problem. I have a Peavey Tmax (I like it, that's not the problem), and as the note that I'm playing is decaying( dying out) it crackles. Sometimes it's not so loud and other times it's really loud. I've tried swapping out cables and basses, and I've pretty much eliminated those as possibilities. It only happens with this amp, too. I have a Trace Elliot that I use as a backup, but it's only 200 watts, so for bigger gigs it's not enough. I'm thinking that it's a power amp section problem, but I'm not very technically inclined. What do you think?

    I have the same problem, but it occurs when I adjust the knobs on the amp, I think it just might be dust inside it, but I'm not sure.

    ive had this happen. Open it up, clean it out, without wrecking. If you do a search you should find how people have even pulled corn pops out of there amps, it's crazy the stuff they pull out.

    I had a similar problem on my old Eden vt.40 head... a low level crackle/distortion no matter what level the amp was set, while the note was decaying... It turned out to be a timing issue between the preamp and the power amp. I really don't know the tech stuff behind it, but when my electronics whiz buddy hooked it up to a scope, the distorion was very apparent in the wave that was produced... There were several trim pots inside, and he made a very minor tweak on one, (maybe a 1/16th turn), and the wave smoothed out. Problem solved... Again, I don't know that tech stuff behind the wizardry, and I'm scared to death to mess with the guts of an amp, but it was a very small tweak that solved a very major problem... Hopefully your issue will be as simple.
