I am trying to find a 1k linear digital pot which has a very low (preferably 0) wiper resistance. Any interface would be ok (apart from just up/down).
I found this article: http://electronicdesign.com/components/active-cancellation-pots-wiper- resistance
which could be a way around the issue.
What I am trying to do, is substitute the 1k pot in the classic fuzz circuit
with a digitally controlled one, and it needs to pretty much go down to 0 Ohm to get the full fuzz effect. I am not sure if the above 'trick' may interfere the fuzz's simple circuit which is extremely sensitive.
Does anyone have any suggestions, feedback or alternative idea?
