I have a Mesa Fillmore 25 head and the the cab that goes with it, a 12 in Black Shadow. An odd noise comes out, much like a very fast tremolo and the sound also becomes muddy when I play the minor seventh interval B (6th string 7th fret) and A (5th string 7th fret) or the major seventh interval B and Bb. It happens with all my guitars. What could it be ? I had some suggestions on another site, I'm looking here for maybe some more infos.
