Does wonders for my amp cab mics.

The compressor section is damn transparent, it lets me dial just the right amount of compression on my mics. Since I use it to record a heavily overdriven high gain amp I don't use too much compression, but nevertheless it provides me just the right amount of compression. The noise gate is a nifty addition.
