The Boss TR-2 Tremolo pedal generates the classic tremolo effect, periodically changing the volume of the sound. The 3 control knobs provide a multitude of effect possibilities: the Depth control determines the strength of the effect, the Rate knob controls the speed and the Wave pot alters the LFO waveform from triangle to square.
