Quick question regarding the curve of a pot being used as a variable resistor (as opposed to a voltage divider). Does the curve matter in regard to effectiveness? Or, does the curve simply determine the "feel" of the pot. I've read on some posts (God knows where in the vastness of the internet) that using an incorrect pot taper will yield a pot that doesn't work correctly. Is that only the case for voltage dividers?
It will work just fine regardless of taper. But you find one taper has a more "even" feel to it.
For example, on the vibe I just built, the Speed pot is 100K audio, and that makes the faster speeds all bunched up into one small range of the pot sweep. 100K reverse audio would likely work a lot better, and you often see the C taper on LFO speed controls.
