-Potenciometre 1 (10k): Guitar input (my guitar produces a 20mV signal. Active pickups produce up to 500mV. This potenciometre allows a smooth control of pulse length in all guitars)
-Potenciometre 2 (next to Pot. 1): pulse length (from 0% or almost 0% to 50%) NOTE: Precious compressor recommended, the length will decrease with tone fadding.
-Potenciometre 3 (bottom one, green output): Wet/Dry. Mix original signal with digital signal.
-Potenciometre 4 (Top right one, orange output): Output volume, don't need explanation I assume.
-Switch (Footswitch): activate pedal. Recommend to use an indicator LED (using free pins of the footswitch) to know if it's activated or not.
