The ToneCore® Tap Tremolo™ pedal gives you pulsating tremolo just like you've always wanted. Using the Tap Tempo feature, along with adjustable dynamic speed control, peak setting, depth, and shape, your tone will chop, slice, and dice like no other. You can choose from three pulse-pounding models: Opto Tremolo, Bias Tremolo, or Stereo Panning.
