Korpa 
The Supa-Trem pedal from Fulltone uses a photocell like an old American tube-amp, but without the annoying ticking sound that plagues other tremolo pedals. The Supa-Trem is extremely versatile—no gimmicks or silly paint jobs—"this thing lives up to it's name" (Guitar World). The tremolo pedal is true bypass with an LED status and speed indicator.
The Supa-Trem's footswitchable Half/Full speed footswitch stays in tempo, allowing Leslie-like moves without losing the song's beat. Another footswitch lets you choose between "Soft" smooth wavering or "Hard" square-wave machine-gun stutter. And there's an internal trimmer to fine-tune the feel of the waveform.
