The Comp Sustain is a nod to the Schaffer-Vega wireless system as used by many artists in the '70s including Angus Young (which was a big part of his sound as the signal was heavily compressed to get the best signal to noise ratio from the wireless system), and also with cues from old fashioned classic valve optical compressors from the '60s hence the “groovy” graphics. Mozztronics used modern electronics while keeping the optical gain reduction element to keep the warmth of these old valve units.
An added DRY control allows you to add in some of the uncompressed signal (an old studio trick called Parallel Compression) and a tilt eq.
This pedal is great on both guitar & bass.
