Title: OS Clone Breathing Pulsations
Post by: BlackFlag1313 on November 25, 2003, 04:28:52 PM
I've noticed with the bias trimpot at different points that I get kind of a breathing, pulsating quality.  Is there any way to remedy this? :?:

It probably just means you're setting the compression threshold too low. Is there a trimpot setting where you get an appropriate amount of compression and no breathing?

This is a natural effect of compressors doing too much work.

It was when the bias was turned back.  I had given the pedal to a friend and that was his complaint - that when the bias was turned back, and the volume was turned down, that it would kind of breath.  I've just always set the biasing a little further up and had never noticed it.

Does anyone know where the biasing is set (voltage wise) to get the original OS level of compression?
Thanks
