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.
