250K VS 500K
Generally, 500K-ohm pots are used with humbuckers and 250Ks are used with single-coil pickups. You can use any value you like, but a 250K will give a slightly warmer tone than a 500K pot. The 250K pot bleeds off some of the high frequencies to ground. A 1 Meg-ohm pot bleeds off even less than a 500K pot, so if you want to hear your guitar "wide open" you may want to try one.
