I love overdrive pedals! Never get tired of trying 'em out. Just discovered the Kasha Overdrive, and it really promises to be a great OD! Here's a link to an article I wrote about it today: http://guitargear.org/2009/08/22/kasha-overdrive/
I don't have the pedal yet, but when I do, I'll definitely post them. He's got a "review" pool and the pedals are with the major rags right now. I'll hopefully get one in a next few weeks.
