So I just got a new (to me) amp setup A Peavey Tour 700w Head, and a 400w GK MBX 4x10 Cab, nothing crazy but its my first "real" amp. Tried it in the store and it sounded good, brought it home and as i really played around with it and i've noticed if i have the highs above like 12 o clock regardless of where the volume is, and i slap, or really dig in fingerstyle the tweeter distorts really badly. If you back it off its fine, but i like having some highs coming through when i'm playing. I figure theres a few possible reasons for this. 1.Because the heads got more power than the amp, but i've heard thats overpowering a cab isnt a big deal if you dont crank it all the way. 2.I suck at EQ'ing and i just have something set wrong. 3.The tweeters blown. Its used so suppose its possible that it could be the speakers bad, but i hope not since i just got it a few days ago. Any ideas on whats doing this?
