What"s cool about the Fulltone Supa-Trem ST-1? Well, we could go on and on. But here"s one big, sticky fact you"ll want to know about. The Supa-Trem ST-1 uses a photo-cell, just like an old American tube amp (gotta love those!)... and manages to do it without that super-annoying ticking sound that other trem pedals plague your tone with. That"s right, the Supa-Trem ST-1 really does live up to its name. So you know, it"s got a footswitchable Half/Full speed control that stays in tempo. You can also choose between "Soft" wavering or "Hard" machine gun-style stuttering with the other footswitch. Plus, the volume control lets you use the ST-1 as a clean boost! Out with your old, lesser tremolo pedal... in with the Supa-Trem! ST-1!
