Or maybe it should say "Diagnosis, madness".
I've been trying to diagnose a problem for the last several months, to no avail. Two separate amps, one a solid state Randall and the other a tube Jet City, seem to be suffering from the same problem: a volume drop off/swell. It almost sounds like a slow tremolo effect. When I start playing, the signal sounds fine, loud and clear. Then, as I continue to play, it gradually becomes more muted. If I stop playing and start again, it goes back to full strength only to gradually mute again. I've tried different guitars, different effect setups, played directly into the amps with no effects, used different cords. I started to think that it might be the power coming out of the outlet, so I ran both the amps and the power supply for the pedals through my Furman power conditioner. Still the same problem.
Any thoughts as to what else I can check?
