Can't pinpoint when it happened, but all I hear is fizz from these amps. I own a few, 2555X, 2203kk, DSL40CR. Don't really care for them all of a sudden. I used to love them. am I going nuts? Maybe losing my hearing? Their cabs maybe? Not sure. Anyone else experience this? for reference, one of the best tones I ever got was with a peavey 6534+ through a traynor cab with v30s. can't stand that head through the Marshall cab with G12T-75s. Maybe thats the problem.
