Interesting pedal ... I like it a lot! Like most people say, it's hard to describe! I sound like a broken record but it's one of those pedals that you notice more when it's off than on. And on is definitely better! Best way I can describe it is it sounds like the tone of the amp when you plug directly into it and bypass pedals. When I insert pedals into the chain the tone dulls. With the EP-Pre, all the sparkle and dynamics return. Very cool. I'm testing it in front of some delay pedals as we speak. Great job Peter!!
