So when I first got my Profiler, I profiled my friends 70's Roland JC120. Ever since then, any time a chord is played at any volume, it sounds like its breaking up (gains on virtually 0 - not on dist setting), but picked notes sound fine. We thought it was the speakers, we just replaced them last week, and its still there. When I profiled, I plugged unplugged the speakers from the amp, and plugged the ext cab outputs into a mesa 4X12 since it was already miced up. Has anyone else had anything similar to this happen or know what it may be? Im hoping we didnt somehow blow a transformer or something...
Damaged Amp due to profiling?

Check your power tubes - try to exchange them. If this doesn't help you must probe with some multimeter a output transformer.
Never disconnect/reconect tube amp speaker when the amp is turned on!! -
JC120 doesn't have power tubes.

Ops - my bad . Yes - this is solid state amp.
Qualified technician should look into it- maybe some of the output transistors are damaged. -

I'd have it checked.
IIRC @Armin of soundside.de told a story when he blew a tube when profiling a non mastervolume Fender amp.
