I know these pedals can be had pretty cheap now days, but would love to have one in a better enclosure.... In the style of something limp bizkit here's the schematic I found. Just how doable would it be?!
Getting reliable M50198Ps could be an issue for diy. For all the trouble (circuitry) required to make the M50198P work to ultimately just have a digital delay and oscillator, not sure it would move too many units.
