I have strat knobs on my jazz (I like numbers on my pot knobs so I can dial in the precise sound I want). I find there is no difference in tone between 1 (or off) and 8. The only real difference is b/n 9 and 10 (or all the way on). I am using 250k cts pots. I am pretty sure the cap is a .44 but it may be a .22. thanks!
