Owned and successfully re-launched by NYC’s pedal manufacturer Pigtronix, Supro is vintage brand mostly known for its amazing sounding amps (you can read its story here). Since its second birth, the new owners have also introduced some pedals (and now – we hear some guitars!).

Their Tremolo has the rather unique quality of recreating the sound of an amp inside the pedal, therefore delivering a tremolo effect with the harmonic character of the ones you’ll find inside guitar amps of the ’60s.

The Supro Tremolo pedal features pre-amp and power amp sections, with an actual output transformer deployed to recreate the magnetic saturation and coloration of the original vacuum tube based effects found in these historic amps. Along with the standard modulation controls for speed and depth, it also features a gain circuit that allows the musician to overdrive the output stage, right where the modulation effects are created. 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 to grind, with magnetic saturation occurring as the power section is pushed into overdrive. As you crank up the gain, the overall output level of the Supro Tremolo 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 overwhelming increase in audio output level.

SPEED and DEPTH controls determine the rate and amount of modulation present in the effect. An industry-standard TRS expression pedal can be used to control the speed of the Supro tremolo. When an expression pedal is in use, the on-board SPEED knob is used to set the maximum value. The rate of modulation is indicated by the pulsing LED status indicator.
