I've been getting a nasty, annoying overtones coming out of my cab m, mostly on note decays, fizzying-out, farting out type of sounds. Tried cab m in every scenario
-pedals with internal preamp
-rack preamps with internal power amp and cab engaged
-amp head/Suhr loadbox with only cabs engaged.
It' coming out of both
-headphone output
-xlr out straight to studio monitors
I'm not feeding it any excessive bass or high frequencies
Tried supplied power adapter and Eventide powermax
....still farting, rattling, fizzying...ideas?
