Fulltone Supa-Trem ST-1 Tremolo Pedal

USA-made optical-style tremolo with footswitchable speed control, hard/soft waveform options, and vintage amp-style pulse

The Fulltone Supa-Trem ST-1 is one of the better-known boutique tremolo pedals from the 2000s, designed to capture the feel of classic American tube-amp tremolo in a sturdy, stage-ready pedal. It is especially useful for players who want warm pulsing movement, swampy vintage rhythm parts, soft amp-like wobble, or sharper rhythmic chop.

This version uses a simple but very practical layout: Rate controls tremolo speed; Mix adjusts the effect strength; the Speed footswitch changes the tremolo rate; Mix adjusts the strength of the effect, the Speed footswitch changes the tremolo rate, and the Hard/Soft footswitch changes the character from smoother traditional tremolo to a more abrupt square-wave-style pulse. It works well for blues, surf, country, soul, indie, classic rock, psychedelic, worship, ambient, and studio use.

This is a player-grade example with visible use, but it has the sought-after older USA Supa-Trem format, large foot-accessible controls, and the classic three-footswitch layout.
