This pedal is based on the repeat percussion effect that was built into the Vox Teardrop guitars and organs of the 60's. (Used by Spacemen 3 to create their hypnotic drones). The difference from the original circuit is the 'pulse width' function. This allows the user to control the intensity of the effect. The first half of the controls range effects the depth of the tremolo effect, turning the knob further will shorten the length of the tremolo 'pulse'.Sounds amazing when combined with other fuzz or other modulation effects.Controlspulse speed : controls the length of the pulsepulse width : changes intensityFeaturestrue bypassboutique quality componentshand made in AustraliaInternational Buyers – Please Note:•Import duties, taxes and charges are not included in the item price or shipping charges.
