It says its an 8 stage all valve preamp with 22 custom mosfets at the output stage. It is two Big Block 750 preamps, but has more power. Its 1400w into 2-ohms, 1200w into 4, and 840 into 8.
I've yet to try it at a gig, but it sounds promising played at home. I don't know where you'd begin offering sound clips, as you can get pretty much any sound you like. Plus I wouldn't know how to record and save digitally!
Its now gone back in the huge mesa sleeve, as the mounting holes didn't line up with those in the Aguilar (pro-tec) rack case. I thought all rack stuff has standard mountings!
