BIG MUFF PI / HALO FUZZ
Variant: Red Army
This is the seventh major version of the Big Muff, released in 1991 after production had moved to Russia. For
the “Green Russian” version, use 470pF or 500pF capacitors for C2, C5 and C8.
Variant: Creamy Dreamer
A boutique BMP from the late 1990s that claims to replicate the Smashing Pumpkins “Siamese Dream” tone.
Part values taken from
Kit Rae’s Big Muff Pi site
. Ignore the connection from Q3’s emitter (Q2 on Kit Rae’s
schematic) - the 100R resistor that sep9V from the filtering and polarity diode makes no difference.
