The George Dennis GD120 Tremolo Volume pedal provides the player with an optically controlled volume pedal that is also capable of crystal clear, great sounding tremolo .... everything from a slight warble to all out surf ...... the classic sound of the 60's, minus the noise inherent in the original designs. Please note, the pedal does not control the rate of the tremolo.

Controls: depth, rate, symmetry, volume, minimum volume.
