I've got an old Crybaby wah-wah pedal which I recently tried to fix by changing the pot - didn't make any difference, so problem must be with circuit board. However as I now own a Kemper, I'm thinking is makes more sense to convert it into an expression pedal rather than fitting a new circuit board.
Have found this guide here, seems the only thing I'll need is a TRS jack: https://www.strymon.net/strymon-tech-c…pression-pedal/
However I also found an old thread on here where a few people suggest replacing stock pot with a "10K linear" pot: Expression pedal for wah
The pot I recently put in my wah was this one (Dunlop Hot Potz II 100k):

I'm not sure what the difference is between this one and a "linear 10k" pot - and seeing as you can calibrate the range of the expression pedal within the Kemper, does it really matter? Or is the problem not so much the range , but that the Hot Potz II has a non-linear response (i.e. that would be curved if plotted on graph)?
