The 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 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.

Scope Analysis
SOFT LIMITING/ENHANCING:
Use this setting with the Optivalve in your pedalboard to give you the maximum headroom available by your amp without crunch it’s input.
Optivalve will enhance your soft touch, and limiting when you attack notes harder.
ACOUSTIC GUITAR:
Slightly open the Tone control to perfectly match the tone of your acoustic guitar, even with higher compression values. The Ratio control can be used fine tune how much you want the Optivalve to affect the dynamics of your signal.
This setting maybe used in mix insert or on the stage “Live” to achieve the desired tone from your acoustic guitar.
ELECTRIC BASS:
With this setting, you can obtain a natural compression that level strings volume and attack.
Set the Tone control to better fit different playing techniques. Slightly open it for slap or pick use.
HARD TRACK LIMITING:
Optivalve can be used as a standard outboard effect on your mix for any instruments. With this setting you can use as a Limiter. Use tone control to better fit the output sound.
In this case, the Input Knob has the Threshold role, use it to set the point where Optivalve starts to limit peaks.
