This is our recreation of the 1967 silicon "Mosrite
Fuzzrite" circuit with added true bypass switching
and LED. The "Fuzzrite" was most famousluy used
on "In-A-Gadda-Da-Vida" but was only availabe for
a limited time before Mosrite went out of business.
The circuit, designed by Ed Sanner was also sold
as the "Guild Foxey Lady" (which was also the basis
for the EH "Axis Fuzztone").
The circuit has a buzzy, agressive fuzz with a kind of
nasal quality caused by the topology of the
transistors - the "depth" control pans between the
outputs of the two transistors (like the "Fugu Fuzz")
but in the "Fuzz Wright" the transistors are out of
phase with each other which creates the EQ peaks
and troughs that produce this unique texture and
Now there is some debate about the "correct"
schematic - most clones (and there are many!)
including ours use the "incorrect" schematic
because the addition of one resistor which the
originals are supposed to have makes the pedal
excessively, piercingly, painfully trebly.
Now I don't believe all the originals had this resistor
but regardless, without it it is a much more usable
effect which retains the out of phase chrunchiness of
the best original units I've heard.
