All of our Stratocater pickups, true single coils, stacks and single coil sized humbuckers, were designed to drop into a standard Stratocaster wiring harness, which typically is wired with audio taper, also called logrithmic taper, 250K pots for volume and tones.
We recommend .047 uf capacitors for strat tone controls, though if less treble roll-off is desired, a smaller value capacitor can be used. Common values besides .047 uf are .022 uf, and .033 uf.
