The BOSS TR-2 Tremolo pedal is a compact and versatile effect unit that provides classic tremolo sounds. It features dedicated controls for "Wave," "Rate," and "Depth," enabling players to tailor their sound to their exact specifications. The "Rate" control allows for a broader speed range than typical tremolo effects, while the "Wave" control can alter the LFO waveform between triangle and square shapes. The "Depth" control determines the intensity of the effect, allowing for subtle to pronounced tremolo effects. Designed for efficiency, this pedal is built to last and is covered by a five-year warranty, making it a reliable choice for both live performances and studio work.
