Hello, to everyone, I'm using the Kemper through a solid state poweramp through a real cab 4x12. I play with a strat with a SD JB on the bridge.
I have great cleans, and I've found some very good direct profiles for mid/high gain crunch-rhythm tones.
During my band's rehearsals (that means we are at relatively high volumes) , during solos, especially when going high after the 10th fret on the high strings, something weird happens, the sound becomes thin and weird, it's almost like having the "direct mix" parameter on at 4 or 5, but it's on 0. It's hard to play, imagine a thin lead sound blended with the direct sound of a bridge hambucker at 50% No power, no fat singing tones.
Very weird because the rhythm sounds are the same profiles and sound very natural when playing rhythm, chords etc. When I was playing with tube amps with the same guitar I had almost the same rhythm tone but the leads where full and normal, without unnatural situations like this.
I tried reducing treble/presence or reducing pick attack but the problem remains, and the sound becomes quite muddy.
Does anyone has experienced such problems? I made a search and found a few threads that mentioned problems like this (they were talking about "thin fizzy sound" on high strings, not exactly what i'm saying but...) Any help appreciated, thanks
EDIT: I dont have such problems when playing with studio monitors at home or recording. Only through real cabs and at high volumes.
