I have a bunch of heads. My normal rig is two of them, a sunn concert lead into a 2x15, and a V4 clone into a 2x15. It's beautiful and gritty and totally wretched sounding in all the best ways. However, I am possibly joining a band in the pretty immediate future where I don't need to be distorted. Anyone who's ever played a v4 knows that thing is gonna get some sweet distortion at about 7, which I can't have. Also not loud enough on it's own. I need to be able to keep up with two guitar players playing two full stacks with two 100w (think jcm800 and laney type of family) heads EACH, but have really clear and powerful tone. I have Mesa and Emperor 2x15's at my disposal, and i'd like to go tube. I need something LOUD. And preferably on the cheaper side. I don't want a SVT. I'm mainly looking for a Mesa 400+, a Sunn 300t, or a Fender Bassman 300 Pro. I don't want to buy new, and would like to spend substantially less than 900 dollars. Anyone have any suggestions?
