User’s Guide

This groundbreaking analog pedal re-creates
the circuitry of a Supro amp from end to
end, including a preamp, phase inverter,
and an actual output transformer. The real
tone of a genuine Supro amp has every-
thing to do with the unique phase inverter
design, Class-A power-amp section, and
the magnetic saturation that occurs via
the old-school transformers found in these
vintage tone machines. In short, the iconic
sound of a Supro amp being pushed into
overdrive has everything to do with the
power amp. There is NO diode clipping
in this design! The following description
of the controls will reference the pedal as
if it were a tube amplifier.
The GAIN control sets the amount of
“preamp” gain in the pedal. As you turn
the gain up, the “power amp” circuit will
gradually be pushed into overdrive. This
control gives you a wide range of sounds
from clean with slight magnetic coloration
to raging overdrive.

The TRANSFORMER switch controls the
amount of dynamic range of the “power
amp” circuit. It switches between two sec-
ondary coils of the output transformer. The
RICH mode gives you a more compressed
and gained up sound. The BOLD mode
gives you more headroom and punch to
your tone.
The TONE control sets the cutoff frequency
of a passive low pass filter at the output
of the “preamp”. When the knob is fully
clockwise, there is no effect from the filter.
As you turn the knob counter - clockwise,
the filter will cut more treble frequencies.
The VOLUME control sets the overall output
level of the effect.
The EXPRESSION jack accepts a 1/4” TRS
cable from a standard expression pedal.
This controls the gain of the “preamp”.
The heel-down minimum gain can be set
with an internal trimmer. The GAIN control
will set the maximum gain. Be sure to have
the expression.

BOOST
There is no better pedal for transparently
driving a tube amp than the Supro Boost. This
J-FET based pedal design delivers up to 20db
noiseless gain boost plus optional High Pass
or Low Pass filtering to contour your sound.

FUZZ
The Supro Fuzz takes a “best-of-all-worlds”
approach to old school fuzz using both N.O.S.
Germanium transistor gain and silicon-based
gain to create a low-noise, high-octane fuzz
box that will leave you deaf and breathless.
