The Mossy Sloth Fuzzy OD is a transistor-based Fuzz/OD hybrid with some unusual topology meant to take advantage of the asymmetrical clipping created by MOSFETs when used as diodes in various arrangements. Though it's called a fuzz and it can add some warm, buzzy fuzz to your chords and riffage, it has strong midrange content and can do some almost-clean, spanky overdrive. The Bass control can be used to clear up the signal or simply ensure that the effect cuts through the mix. Like all of my dirt pedal designs, it also provides a mighty boost to push your amp into its own breakup, and much attention has been given to smooth touch-sensitivity and volume knob cleanup.
Please check my website, jonpattonmusic.com, or the forums I hang out on (Madbean, DIYstompboxes, and BYOC) for the schematics and layouts if you're interested in building your own.
