Fulltone Supa-Trem ST-1
Unknown brand · pedal
The Fulltone Supa-Trem ST-1 is a true tube-driven tremolo pedal producing warm, organic, vintage-style volume modulation with genuine tube character rather than a digitally simulated pulse. Volume and Speed controls shape the pulse, and an optional ramp function lets the tremolo speed accelerate or decelerate smoothly rather than switching abruptly between rates. Its tube circuit gives the pulse a rounder, more musical shape at both slow, deep settings and fast, choppy speeds compared to solid-state tremolo circuits. It suits players wanting authentic, amp-like tube tremolo character in pedal form, particularly for vintage surf, blues, and classic rock tones.
