A very tidy example of the Boss TR-2 Tremolo Pedal.
Finally you can get those vintage, warm tremolo tones that you've heard produced by many classic amps on hundreds classic records - in a compact stomp box. The simplicity of the TR-2 doesn't leave much to go wrong. Just set the speed and depth and you're away! The TR-2 has adjustable wave shape to add the final definition to your tone.
