To the OP...

You came to a great place here, and every one of the guys that previously posted to your thread are right on.  I'm a Mesa owner as well, have a 2/12 Maverick with nary a Mesa speaker or tube in it, along with a one of a kind custom bias mod, and have several boutique amps, along with a collection of a few hundred vintage tubes, but none of my other amps are as versatile in both tones and ability to sound great from small rooms to large with the same amp like the D-style clones previously mentioned.  I have a 50w HRM with a c-lator, and a 50w OTS built by Marsh with c-tone boards that I run by itself with no fx buffer, it is also amazing in the range of tones it can do at small to large room volumes.  I'm glad to have both of these middle of the road D-style  amps.  The various switches and gain and tone controls offer an amazing tone palette.
