WARNING!!! If you're not familiar with the Mesa m-2000, this might not make a whole lot of sence...you've been warned. So, I got my m-2000 today and to my dismay, the first time I plugged the sucker in, all I got was a loud loud LOUD screaching noise. I was more than a little disappointed, so to make a long story short, I took the dang thing apart which is not something I reccomend without having a large quantity of time on your hands...it's a pain in the butt. I checked the pots and fixed the main output pot which is what was causing the nice loud screeching noise. I then put it back together (minus the top cover) and fired it up. The tube channel works great but if you try to use the fet channel by itself, there is very very little volume. Now, if you put it into mix, the volume sounds fine, but it could just be the tube channel. The volume drops again if you turn the mix knob almost all the way to the right. I'm at a loss for what else to try...any of you other guys have some ideas for me?
