Mesa Boogie Mark IV. Totally amazed at it's capabilities. Very compact (although as heavy as my Marshall 4x12!!! I think it's actually made of lead!) Plenty of bottom end from EV. Nice cleans, great crunch, nice singing sustain. 6l6/el34's, switchable class A, variac, triode/pentode, push pull fat, bright, bass shift, mid shifts, several DI outs that sound great into pa/ear monitors!, switchable reverb tank, 4 sounds at the tap of a foot.
Honestly, it can do 90% as a good as a Deluxe Reverb clean, 90% as nice drive as my plexi cranked, 90% as nice as an ac30 cranked, great smooth articulate dumble like od's, then of course Santana like lead tones. Actually it's the most articulate amp I've ever used, pick attack can take you so far. Amazed. Just how they made something than get's within 10% of all the greatest amps is beyond me.
I've always hated multi-channel amps, always preferred a single channel amp, a one trick pony that has a truly great trick. This has so many. If you get the chance give one a whirl.
