Sorry. Mines toast! No doubt. Gain at 3. Volume at 3. No pedals, with pedals. Pedals on input side, pedals through effects loop. Plugged into my Hartkes. Plugged into the Acoustic 301. Crap. Nothing but crap. Definitely something wrong. Amp is no louder than when set at noon. Seems fine till you crank it and there's no discernible volume increase after 12:00. Luckily my bandleader is loaded. Hello GK 550 fusion.
I certainly believe I'm just one of the unfortunate few so I'm not gonna bash Peavey, stuff happens. What's frustrating is I've been giving the amp the benefit of the doubt for over a year now thinking it was something I was doing wrong. Time wasted. Now it's weeeelll out of warranty.
