I wanted a Peavey Rock Master preamp since I heard of them some years ago. I didn't need it, but GAS is GAS.
The unit is pretty solid. It goes from a crunch to a really high gain and tight sound. The unique thing that I don't like, is that EQ is a bit silly.
They go from zero mids to a lot of mids in a second.
Appart from that, I'm really happy with it, and I will pass it through my Axe Fx (thanks Sean!) for recording.
Do you guys have any idea about how to mod it?
