Are pots from PRS Accessories the same as used in S2 models?

The pot listed there is the core pot, which is a higher spec than the S2. The S2 volume pots are from Jin Sung, who is an OEM provider. I haven't seen their stuff for sale aftermarket.

I think you'd be quite happy with the core PRS pot. I just sat here alternating between spinning one of those and a Jin Sung from an S2 and they feel close. The core pot is better built and should last for a long, long time.
Even better! I figured since it said only "PRS designed" that it might not be part of the Core line.
