I put in the super switch and Anderson H3 last night.
The H3 sounds great, much better than the JB, fuller, thicker.
I went with a 510k resistor, but I think I am going to measure my pots that I took out. The single coils are now a bit bright and crisp. I think lowering to a 470k or lower may do the trick. Out of 4 CTS 500k pots, one was 535k, the others were 475k, 463k, and 454k. Must be +/-10% pots.
