Hey all, I played through an Ampeg B2RE this weekend into a Sunn 215, and my heart skipped a beat, it sounded so sassy I wanted to squeal. Ran through a Bluebeard (boutique version of a Russian Big Muff) and it just rocked . So! I wanna buy one'a these heads. Trouble is I've only played the one, and frankly can't seem to dig up much of what differentiates the three because some subtleties in wattage and price . Are these guys essentially the same tone, different wattage? And are there comparable amps out there with similar big, sultry tone? I've wanted a Coliseum for a while now, but these Ampegs rocked my socks off. Any help with decision-making here would be greatly appreciated, as I'd like the biggest bang for my buck, assuming all three sound the same of course. Thanks to all!
