From the vendor
A small simple to put together drive based upon the old rounding error project. Goes from a punchy boost to a splattery octave fuzz when maxed out.
The Small Format Drive (SFD) was made to get a bit more millage out of the Rounding error circuit. Adding in an input bass control and Tone control unlocks a wooly drive, some punchy boost, and a splatty octave fuzz.
