Cryogenically treated pot allows you to blend the neck and bridge pickups together. With the blender, your guitar will have a volume, a master tone, then the blender. With the blender turned to 10, the guitar has a normal Strat® switch set-up. With the blender set to 0, the neck and bridge pickups are connected in switch positions 1 and 5. All three pickups are connected in positions 2 and 4, while position 3 is still just the middle pickup, giving you 2 extra sounds. This is a true no load pot. Wiring diagram included.
