Yes I agree with you that getting levels right seems more difficult that finding the right tones.
In fact, people can excuse a non-ideal tone, but they won't appreciate too loud or too soft volumes popping up in the middle of a rehearsal.
I would like to cut through to the chase and find a downloadable set of tones for typical cover songs for typical bands like Blink182, Guns and Roses, U2, Tom Petty, Hendrix, Nirvana that I can use on the Firehawk. Does such a thing exist?
I understand if you use studio quality headphones, the volume setting can be done at home??
