Title: Alt presence control for cathodyne or floating paraphase inverter
Post by: navdave on March 10, 2011, 10:04:49 am

Could the values of this depth control be tweaked to be used as a presence control for a cathodyne or floating paraphase inverter?

navdav have you been looking at those dirty SLO poweramps again shame on you.  :l2: I keep thinking someday I will use it I hope someone answers your question its seem like it would have a use in several types of designs what was your thoughts on it, or what were you thinking of using it in . Sorry Im always trying to learn something even if its just how other people are thinking about circuits.
Thanks Bill

Yes. The type of PI is irrelevant. It is a completely separate issue from from the presence/resonance/depth controls you choose to use.

Hey Merlin any suggestion on what value pot and cap I should try? I tried a 100k pot with a .01uf cap all it does is change the dampening no matter what value cap I used
there was no real tone change.
