45+ years playing bass. I finally fried my tour 700 after 500+ gigs. Finally got this amp. Excited, but disappointed. It is powerful!!! Has all sorts of bottom! I play Gibson SG basses, which are bassy to begin with. I can't seem to dial in low highs, or hi highs for that matter. I tried it out through my BW cabinets, and then with 2 4 x 10 cabs. It seems this bass amp is a one trick pony - all bottom. The small lables under the push buttons are unreadable when on stage, with lights! So, I keep a small flash light on stage when I want to make adjustments. I think a standard slider EQ would have been better. The parametric is confusing. Back to reading the owner's manual. BUT, I'd buy it again! I'll get my tone dialed in eventually. Lightweight and LOUD! So it's a keeper.
