The Boss TR-2 Tremolo pedal delivers that classic pulsating effect that has defined everything from surf rock to indie and ambient guitar. Three intuitive controls let you shape the effect precisely: Rate sets the speed, Depth adjusts the intensity, and Wave dials between smooth triangle and choppy square wave shapes.

At lower settings, you get a gentle, swaying pulse that adds subtle movement to clean tones and chord work. Crank up the depth and rate for dramatic, staccato-like chopping that cuts through a mix. The TR-2 handles the full range of tremolo sounds with the reliability and build quality that Boss pedals are known for. A timeless effect that belongs on any pedalboard.
