This is a 4-pack of our CT-450S2179A blender pots. CTS pots are the standard of the industry for good reason. Used by Gibson and Fender for many, many years, they are easily the most trusted brand in guitar pots. Ours are made specifically for us by CTS, to their tightest tolerance (10%). Appropriate hardware in included: lockwasher (use inside the guitar), flat washer & nut (use outside the guitar). The right parts to get the job done.
Blender pots are typically used in Strats. Originally conceived by Lindy Fralin, they replace one of your Strat's tone controls, allowing you to subtly blend your neck and bridge pickups. You can have both fully on - like a Tele - or you can have either one fully on and blend in the other to your liking. Lots of subtle tonal shading! Simple installation, wiring diagram provided.
