a black russian Big Muff Pi made
higher quality components, and with a 2 knob passive
tone stack to take the place of the original one knober.
it sounds fantastic, and is much more useable. also
has some power decoupling/ filtering so that a power
supply may be used, and the box is a far cry form the
shoddy at best construction of the original...i know of
at least five people who buy muff after muff, do to the
fact that the black russians fall apart under normal use
I thought wrapping it in grass was pretty funny............
