The Fulltone Supa-Trem1 is a tremolo pedal, the effect that rhythmically varies a pedal's volume to produce a pulsing, surf-style swell. Guitar.com described it on its debut-era reputation as having "made (sine) waves with its simplicity and lush, amp-like tones"1. The pedal first appeared in 1996, making it one of the longer-running designs in tremolo pedals1.
How it works
Alongside its tremolo effect, the Supa-Trem1 can offer up to 15 dB of clean boost with the "Mix" knob set to zero, according to Fulltone1. That means the pedal can be used as a straight volume boost when the tremolo modulation is dialed out, a useful second function on a pedalboard where a clean lift is needed for solos.
Clean boost
Beyond tremolo, the Supa-Trem1 can double as a clean boost: with the "Mix" knob set to zero, it offers up to 15 dB of boost, a use that overlaps with dedicated boost pedals1.
The Supa-Trem family
The Supa-Trem1 is part of a family of Fulltone tremolos, which also includes the Supa-Trem2, the Supa-Trem Jr (also listed as the Supa-Trem Junior) and the Supa-Trem ST-1. Like the Supa-Trem1, these pedals trace their lineage to Fulltone's opto-based tremolo design, and players comparing them will find the Supa-Trem1's clean boost feature, up to 15 dB with the "Mix" knob set to zero, is one of its distinguishing traits1.
