Today I just picked up a Mesa 400+, and to say the least I'm impressed, much more so than I had been with previous experiences. It has JJ tubes in it, which are nice and warm and better sounding than the stock ones I've played before. Extremely warm, I can get overdrive at just about any volume. The EQ is a nice feature if I ever need it. The two inputs are very similar in sound, but you can tell the differences when cranked. I'm running this through an old EV 215, pics coming soon hopefully.
