Hi All,
I'm inventing something for the effects pedal market. As in distortion pedal, delay pedal etc. I know only a bit about electronics and circuitry. Engineers will help me later. For now I'm just trying to understand this:
Is it possible to remove any given pot from a pcb, as in the "Time Knob" on a delay pedal, and replace it with a digital means of parameter control?
If so, how?
Can the now empty points extruding from the pcb be connected to a DAC of some sort, thereby opening the possibility digital control?
I'm knew to this forum thing.. please be gentle.
Thanks in advance.
Pete

Yes but the how of an existing design will be different to that of a design from scratch.

Also: it depends on what the pot does.
A "volume control" type pot with one leg grounded or referenced to ground is easier; a fully floating "isolated from everything else" pot such as a mechanical carbon track is harder.
In fact, designing some kind of digital time/speed/whatever is probably much better than trying so replace an existing carbon track with a brass wiper ... which was already suggested above.
