That's a different problem. "not loud enough" is not the same as "doesn't sound good", which is what it seems you're saying.
I mean it's a little of both. Clean/low gain/even medium gains sounds okay. It's the high gain stuff that doesn't sound good to my ears. Mr. Kemper is right that he said FRFR mode is provbably better for high gain stuff and I would agree, but then you lose the amp in the room idea. Hence, why I'll just stick with buying a regular 2x12 v30 cabinet for playing DI profiles in person and headphone studio profiles at night.
