Oak-Grigsby made switch. 4 way for Tele. Offers the 3 usual positions but the 4th offers both pick-ups on in series, producing a fatter sound. Screws included.

We have 2 versions of this switch first as original and then Specialised for Tele where we have machined the shoulders.  If you are using with a standard Tele control plate then the slot will not allow the switch to trave far enough to engage positions 1 & 4. 

The solution is to lengthen the slot which we would not advise on plated control plates as the plating will flake or to machine the shoulders which we are happy to do for you just select this version in the drop down menu below.
