i own a marshall vs262. it has a clean channel, od channel, reverb, and chorus. i've had it for a good 3 years or so and never had a problem with it. lately though my overdrive seems to be very flat. the tone quality has recently dropped real badly, and messing with all the eq's doesnt make much difference. hell, it's even QUIETER than my clean channel even when i turn up the gain and volume higher than my cleans. it's really weird.

anyone have an idea whats up with my amp?????
Yup. Get a new 12AX7 tube. Should cost all of $12 at most.
