From the source:
Ram The Manparts is a LM386 (a power amp
chip) overdrive that we built to allow guitarists and bassists to not
only drive an amp HARD, but also to add some textures and features to
stand out! The voltage sag allows the user to drop the voltage below 9V,
creating a glitchy, sputter, Velcro-like sound. Keep it clean, make it
grindier/heavier, or make it glitchy…the choice is yours, dude.
The pedal has since been discontinued and not the cheapest when buying used if you can find them.
