GURU’S OPTIVALVE Tips

Optivalve may be used in several different ways. It can run as a pedal on your
pedalboard, or used as studio outboard gear for your recording tracks, suitable for
Guitar, Bass, Acoustic Guitars, and any other instruments.
The followings settings are made with Optivalve in front of the amp, positioned at
the end of the pedalboard’s chain.

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.
