Should I use 250K or 500K pots?
You can theoretically use either 250k or 500k pots. They will both work. 250k pots are typically used with true single coil pickups, but can be used with stacked single coil or humbucker pickups. 250k pots will tame the highs a bit, while the 500k will allow the pickup to be a bit brighter. We usually suggest 500k pots with humbucker pickups. If you have stacked or humbucker pickups that you’re mixing with true single coils, we would suggest using 250k pots.
