Introduction
Congratulations on your purchase of the Rocktron
Pulse Tremolo.
The Pulse Tremolo pedal provides a very economical way to get
that expensive classic tube tremolo sound in a small box. Typical
modern tremolo devices are created electrically using VCAs. The
Pulse creates an amazing tremolo with modulated light and static
light. Yes, you read that correct, we use light to create the tremolo
effect! Using light for creating signal modulation via a photoresistor, 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). The result is a
smooth non-symmetrical tremolo which closely approximates
classic tube tremolo properties. A SPEED control varies the rate
of the tremolo, while an INTENSITY control determines the
amount of the effect. A switch is provided that lets you choose
triangle or square LFO pulse modulation waveforms.
The easy access battery compartment will make changing batteries
during a gig a breeze. We have also equipped it with a super
bright blue LED so you will know when the pedal is on...it is also
just plain cool!
Enjoy
