October 14, 2008
This tap tremolo was made to reproduce the rich classic tremolo sound of vintage fifties tube amps

The unit comes in 16-gauge steel housing with bypass and digital tap tempo switches, and uses a pure analog signal path. Control knobs are large but not quite “toe-tweakable” size. The Depth control, at the heart of the traditional tremolo sound, has a wide range that goes smoothly from subtle to pulsing tremolo; the Wave control offers continuous waveform variation, from sine to triangle to square.
The unique Shape control for which the pedal is named is a very cool feature, allowing you to control the ratio of volume swell to decrease, enabling the creation of very appealing envelope-type sounds, from percussive and piano-like chimes to backward-sounding pulses. The Rate knob works in two modes: in rate mode, it is a speed control that goes from 1 to 20 cycles per second. In ratio mode, the Rate knob controls the tap-to-note ratio, while the tempo is set by the tap switch.
The sound was indeed lush, and gave me no noise. I had a lot fun dialing all types of effects, some of which were truly inspiring. This is much more than a tremolo. – CB
traditional tremolo effects bore you.
you’d much rather stay bored.
