I built this circuit about a year ago, in a hand-painted DSOTM-themed enclosure. I was terrifically underwhelmed by the circuit. It sounded to me like a generic distortion…or a FF setting in an early-2000’s digital modeling amp. I’m not sure if it’s the actual pedal, or if building a Si Sunface kinda skewed my expectations. Also could be a didn’t spend enough time dialing it in. Glad yours worked out, though. And your artwork is great, and accurate…
