Got my Pro co, Keeley modded, The Rat2 (I think, lol) in the mail. I am loving it. It's a one trick (2 at most) pony but so far, dynamite. I've settled in on the Mighty Mouse mode, at least on the Mesa. I have it hooked up to the Mesa Lonestar and it's definitely super crunchy. I use the mesa for day to day playing and the JCM 800 for recording. I plan on hooking it up to the Marshall soon to see what's what! Damn, heavy tone. I love it.
