I have a Mesa TC-50 that I grabbed because my Mark V is crapping out, needs some work. Up loud the bottom end isn't an issue, but an MXR 10 band EQ in the loop fixes pretty much any possible issue/need you need to deal with. I've used one live and had the master past the halfway point, so pretty loud. At that point the clean breaks up a bit and the lead boost runs out of headroom but it's already blasting loud at that point. It's a real solid amp and killer for the price. I actually have mine on Reverb right now.
