The Emerson Blender wiring harness (MFG# S5-B-250K-PREMIER) for Stratocaster® and similar guitars has 1 volume, 1 master tone, and a Blender pot. In the neck position you can blend the bridge pickup in as much as you want. In the bridge position you can blend the neck pickup in as much as you want. In positions 2 and 4 you can have all three pickups on at once. The nicest part about it is the fact of it being so user-friendly. Everything else seems to be hard to use on the fly.

Installation Tips for Knobs on Split Shaft Pots

US Spec Emerson PREMIER PRO split shaft pots are made to fit USA Spec 24 spline push-on knobs. Some USA & Import Guitars will need new USA Spec Knobs as even some US makers use import spec parts which will not work with our pots. We recommend that you don't rush the knob installation process. If your knob is too tight and is not going on, slightly crimp together the top of the potentiometers shaft ever so slightly so that when you go to push on the knob you don't damage the pot shaft by exerting too much downward pressure.
