The Fulltone Supa-Trem ST-1 Guitar Effects Pedal puts the option of a classic amp sounding tremolo at your feet and includes a clean boost. For years people have been turning the ST-1’s MIX knob down all the way, opening the pedal, and turning up its internal volume control to maximum, and using the Supa-Trem as a very subtle clean boost. Now a VOLUME knob can be found the outside of the pedal offering the option of increasing the available gain to around 15dB... allowing the ST-1 to pull double duty as a stellar clean boost. One reason the Supa-Trem sounds so good is that it uses a wonderful Analogue Devices JFET AD711JN at the heart of its circuit, giving you a warm yet clear tone when your pedal is turned on.
The ST-1 also employs a custom-designed Fulltone Opto-1 photocell with an extremely fast recovery time which no other manufacturer can match. This makes it behave just like an old 1960’s American tube-amp, but without the annoying ticking sounds that plague amps and other tremolo pedals. The Supa-Trem is the most versatile tremolo on the market, sporting True-Bypass with Blue ON/OFF L.E.D. and a Red RATE L.E.D. showing your speed at all times (even when pedal is OFF) so you can drop right into the song at the correct tempo.
