The Supro Analog Dual Mode Tremolo is an all-analog tremolo pedal that recreates the modulation effects found in Supro's 1960s amplifiers. It offers two modes, Amplitude and Harmonic, and is built with preamp and power amp sections, including an actual output transformer deployed to recreate the magnetic saturation characteristic of historic Supro amps1.
What it does: amplitude and harmonic tremolo
Tremolo comes in two main types. Classic tremolo changes the overall volume of the guitar, while harmonic tremolo alternatively changes the volume of the bass and treble frequencies, and was initially developed in Fender's "brown face" amps2. The Supro pedal carries both, letting players switch between what Pedal of the Day calls swampy tremolo sounds and psychedelic modulating tones1.
The circuit references the legendary tremolo circuit built into original Supro amps, and the pedal accurately recreates the modulation effects found in those amplifiers of the 1960s1.
Controls and expression input
| Control | What it does |
|---|---|
| Speed | Sets the tremolo rate; adjustable by expression pedal1 |
| Depth | Sets modulation depth1 |
| Gain | Gain control with automatic output level compensation1 |
The pedal features an assignable expression pedal control to adjust the Speed function, so the rate can be swept by foot during a performance1.
What reviewers said
Pedal of the Day, in a 2023 feature, described the pedal as featuring "the absolute most authentic tremolo effect ever offered in pedal form" and concluded that "it sounds amazing, taking you on a modulated journey into the unknown"1.

Questions
Is the Supro Dual Mode Tremolo analog?
Yes. Pedal of the Day describes it as an all-analog tremolo, allowing players to switch between swampy tremolo sounds and psychedelic modulating tones. It is built around preamp and power amp sections, including an actual output transformer, to recreate the magnetic saturation characteristic of historic Supro amps.
What is the difference between amplitude and harmonic tremolo?
Classic amplitude tremolo changes the overall volume of the guitar. Harmonic tremolo instead changes the volume of the bass and treble frequencies against each other, and was initially developed in Fender's brownface amps. The Supro pedal offers both modes.
Does the Supro Tremolo have a real output transformer?
Yes. According to Pedal of the Day, the pedal features preamp and power amp sections, including an actual output transformer deployed to recreate the magnetic saturation characteristic of historic Supro amps.
Can you control the Supro Tremolo speed with an expression pedal?
Yes. The pedal features an assignable expression pedal control to adjust the Speed function, so you can sweep the tremolo rate by foot while playing.
