I am looking at buying a mesa V-12 but I can't find any reviews. I'v played every other high powered models that mesa makes but I have not played the V-12 or the Big block 750(basically the same or so I'm told). my local dealer can't get either in with me buying them first. I play jazz, alternative, and a lot of fast metal. Is this good for this? I seems like it world be great each these styles but maybe their is something better out there for $1700. All input would helpful thanks.
