Ive been looking into Mesa Bass amps for a while and would like some more inputon people that have played the others that im thinking of. I have played the M-Pulse 600 but am also looking at the Basis 2000 and the Big Block 750. I am looking for a good rock amp (style of music is like Alter Bridge/Creed/Submersed) that would have a good tone for my type of music. I really like what i read about the discounted Basis 2000 and its many features and dual preamps, but the simpleness of the BB would be awesome as well. However the Big Block 750 is a new model so im assuming that should be better beacause i cant imagine how they could make a new one with less quality than a discountinued model. From playing the 600 i didnt really know how to describe it until i read someone else talking about it and i totaly agreed. It does seem to have a "hi-fi" type sound. Almost a tube emulation or something. I want a bass amp with some great low end, that will sound good for rock and i want to know what you guys think would sound best with my type of music etc. Thanks in advance.
