This switch adds neck/bridge pickup in series in position four for a thicker tone and more volume. The switch comes with 2 round-head, nickel Philips mounting screws. If you need countersunk stainless steel or countersunk gold screws to fit your pickguard, or a switch knob, you can order them separately.
This model is US made and is the one used as original equipment on some of Fender's Telecasters. Distance between screw centres is 41.11mm.
