Guyatone HD2 Harmonic Distortion w. mods - Verified

[anders]

Verified layout of an interesting Big Muff variant with op amp input and output stages and a couple Ge diodes in line (see Boss HM2) between second clipping stage and the modified tonestack.

Nice job again, Anders. I like the mods too. The original has a Muff tone stack stuck halfway and it's very scooped. This will make it far more usable.
