For those looking for a truly vintage sounding effect. With only three knobs you can dial in a wide range of tremolos from sweet and subtle to hard and deep. The tuning control defines both the shape and depth of the tremolo. The rate control can take it from a walking pulse to a choppy helicopter. A buffered level boost is included to match the output for deeper modulation settings.

The pulsating heart of this pedal is light and photoresistor technology. The analogue oscillator has been completely electronically isolated from the signal by means of a optical coupler. On-board is a light which fades in an out at the depth and rate of the tremolo which is pointing onto a light-dependent-resistor. This resistor limits the level of the signal that can pass, acting like a guitar volume control knob.

The LDR has a slightly delayed rise and fall response time which makes for a very natural sounding pulse. This smoothing effect also takes off the harsh edge of the wave that the oscillator would normally make when it changes direction. By using optical coupling and a thoughtful layout, there is no oscillation 'ticking'. The oscillator is completely switched off in bypass mode to guarantee no bleed through.
