Reply to Changing a few knobs on the S4 ~possible?

Hey everybody, I was wondering if anybody could tell me, is it possible to switch a standard pot with an encoder without having to do any major alterations to the circuit design....

Specifically what I would like to do is switch the effects knobs on the S4 to encoders.....the reason being I hate having to reset the knobs so they match the software every time I change an effect......for me it would just be so much more logical if encoders were used here so I can just switch effects, hit reset, grab a knob and start tweaking......

Thanks for the help...
