From the post

The latest incarnation of a very popular classic Skreddy pedal. Thanks to mmolteratx on FSB for the traced schematic.

Info about Marc's original:

A faithful recreation of that old-school big box that gave us our start Creamy, sustaining, amp-blowing-up, huge distortion with a grainy, ear-pleasing, low-fi edge and just the right amount of 'hair' Heavy does not have to mean harsh or unnatural or even modern Finally a tone control that is actually useful and powerful, yet does not sound bad at any setting Makes a single-coil pickup sound more like a humbucker, yet doesn't completely obliterate the guitar's tone Makes a clean amp sound like a dirty, cranked amp, even at low volume--preamp or power-tube distortion not required.

The tone of these transistors is nearly identical to the NOS units the original Mayonaise used (they look the same, too). Just a couple of minor capacitor tweaks take it the rest of the way there. Made of the same types of parts as used in our first product ever, which was a sonic clone of the circa 1971 "triangle knob" version fuzz box that used the legendary and unobtainable FS36999 transistors.

Has all that original pillowiness, grit, compression, and near infinite sustain as the original.
