I play a Marshall AVT150 head into a Peavey 2x12 cabinet. I like the amp a lot, but lately I'm noticing a problem with my clean tone. One of the things I liked about it when I first got it was the smooth and rich clean tone. Starting about a month ago, though, I noticed that the clean channel would distort when I play chords with a strong attack using the neck pickup of my guitar (it's a humbucker). This is not a pleasant-sounding distortion, either. It is only audible on the attack of the chord (single notes don't seem to push it hard enough to cause the problem). Using both pickups, the problem is almost not there, but it's there. Haven't noticed the problem with the bridge pickup. Turning down the gain on that channel does not help at all, oddly enough. I think it may be worsening. This is a hybrid tube/solid state amp; it is possible that the preamp tube needs to be replaced, or do I have a deeper problem?
