Thanks alot for posting this schematic. I bought the hype of this pedal and bought it, and I wasn't impressed. I got it used, and it sounded dull to me. I followed your schematic, and replaced the two caps in the treble section, they were 222j (2000pf) caps, and put in the value 561 (560pf). Holy cow, it now has more of a plexi vibe to it. I now dig this pedal.
