The stock MT-2 has a really bad mid range harshness to it, it almost hurts to listen too. I think SandMan and myself are using the wrong word to describe it, with the stock MT-2 you can't eq this "harshness" out, even if you scoop the mids, sweep 'em or whatever you try. With the Keeley mod, that harshness is gone, and the bass response is a lot fuller. All in all it's just a WAY better pedal. It now finds it's way in my efx chain more than my Metal Muff. I can't wait to send in my SD-1 for the stacked mod. It's got a Germanium chip in it.
