The Gurus OPTIVALVE Tube-Optical Compressor pedal is the last word in compressor pedals with all the advantages of the legendary studio outboards that have made history in music, but more versatile and easier to use. Use it in different ways as a studio outboard, or on your pedalboard. As a standard compressor pedal to bring out the tone suitable in various styles: funky, blues, rock, etc. Use as a limiter, to obtain maximum clean volume from your amp without adding crunch to it, or as an incredible enhancer of your tone.

Use the “See thru Magic EYE” to view the compression reduction level. Use it with your guitar, bass, keyboard, acoustic guitar, or as real outboard for your mixing tracks.
