I just recently bought the axe fx standard and I am having a problem getting a good sound. I know they're in there and I am not that unexperienced with equalization. The highs are too shrill like and piercing and there is that digitalis sound coming through on clean and heavy rock patches. I have a peavey 50/50 power amp with the presence turned all the way down. I am running a bogner 212 cab and a mesa recto 212 cab. Any advice?
