I often practice with my band in rehearsal studios that already have the Ampeg head with that monster of a 8x10 cab, and honestly I have always hated it with a passion. Whenever I plugged it sound like I was getting ready to play DRI or some other hardcore band from the 80's .Not that there is anything wrong with that, but it's just not the tone I want for top 40 dance music. I use an Ampeg SVT III- pro with a BagEnd 1x15 and alway loved it, but tonight I had to play trough one of these beast again. I said maybe I just hate the way the other people set it, so I set it like mine Flat, I adjusted the gain a little to 8:00 oClock and turned up the master and low and behold , I got G.A.S I could not believe that my narrow-mindedness was keeping me from liking this Amp. Here is the problem, I wanted a smaller amp to lug around to gigs. This is not small, so would a 4x10 get similar results? I have my trusty Zoom B3 now I'll have to see how that 8x10 sim sounds. I was probably better off just hating it!!! Just saying.
