can somone show me the ideal pot for the mark III r2 mod?

[JimAnsell]

there are so many different size pots out there, i want to make sure i get the right one the first time. I want to do the mark III r2 mod. i'd like to use the existing "reverb" jack hole on the pack pannel that is currently plugged, for the pot. could someone link me to the ideal pot for this?

thanks

Measure the size of the diameter of the hole and get a corresponding sized 250K audio taper (logarithmic) pot.

Alternatively, according to looking around the threads on here the correct part should be Mesa part number 591048

Hope that helps!
