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.


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.


Optivalve can be used as a standard outboard effect on your mix for any instruments. With this setting you can use as a Limiter.
