The Pulse provides a very economical way to get that expensive classic “tube tremolo” sound in a small box. While typical tremolo devices are created electrically using VCAs, the Pulse is created with light, using light for creating signal modulation via a photo-resistor – an LED lights up and the photo-resistor changes the output volume on the Pulse in relationship to the light intensity. An LFO (low frequency oscillator) pulses the LED at a given rate and a given wave form. The light travels to the photo-resistor causing it to change resistance value, which in turn changes the gain output of the internal amplifier (op amp). If all this sounds very technical, what you really need to know is that the result is a smooth non-symmetrical tremolo which closely approximates classic tube tremolo properties.
