The Supro Tremolo pedal emulates the sound of a Class A tube amp circuit and delivers two distinct flavors of tremolo. Select Amplitude mode for the iconic sound of bias-modulated power tubes. Switch over to Harmonic mode to conjure the sound of early-'60s Fender amplifiers. Use the Gain control to drive the output transformer into rich sonic saturation — the automatic volume compensation will ensure adding gain doesn't boost volume. Factor in the expression pedal input for control over the tremolo speed, and it's clear the Supro Tremolo pedal is one of the most versatile tremolo effects around.

AMPLITUDE mode provides the traditional swampy, tremolo sounds generated by bias modulating the power tubes in the original Supro amps.

HARMONIC mode provides the psychedelic tones of Leo Fender’s brownface and blonde amps from the early 60’s. We’ve implemented Leo’s unique “harmonic tremolo” effect within the output stage of the pedal to create an “amp-like” modulation experience.

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, the Supro Tremolo 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.
