Speed:
Sets the rate of modulation.
Amplitude / Harmonic:
Selects one of two distinctly different modulation effects. Amplitude mode
provides the traditional power tube tremolo sounds found in the vintage Supro amps from the 40’s.
Harmonic mode features a pair of crossfading filters to recreate the uniquely psychedelic tones of
amps from the early 60’s.
Expression Jack:
Accepts a 1/4” TRS cable from a standard expression pedal. This controls
the Speed of the modulation. The on-board Speed control will set the maximum range of the
expression pedal.
Your Supro Tremolo pedal comes equipped with a 9V battery that is accessible from the side-mounted
battery drawer. A 1/4” TS cable must be connected to the input jack for the pedal to power up.
The Supro Tremolo runs on 9V power only.
Gain:
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 the signature Supro power-tube overdrive. As the gain level
is increased, the output level is automatically compensated in order to maintain consistent signal
level. This allows the musician to use the Gain control to alter the texture of the modulation effects
without an unwanted increase in audio output level.
