The OPTIVALVE Tube-Optical Compressor Pedal is the final word in Compression Pedals with every advantage of the legendary Studio Outboards that have made history in music, but even more versatile and easier to use.

It can be used in different ways, as a studio outboard, or as an indispensable part of a pedalboard.As a standard compressor pedal to achieve typical tones suitable in funk, blues, etc. As a Limiter, to obtain the most possible clean volume from an Amp without crunch it, or as an incredible enhancement of TONE.

Look into the Magic EYE, the Compression reduction level meter and use it with a Guitar, Bass, Keyboard, Acoustic Guitar, or as a real outboard for mixing tracks.
