I just picked up a 52 Tele Reissue and it's the nicest guitar i've ever played in my opinion but I need help figuring out the selector switch. I know the first position controls the bridge pickup. The middle position controls the neck pickup with tone and volume controls. The 3rd position i'm not really sure what's going on. I think it's the neck pickup with no controls. Could someone please explain in some detail. Also, I am aware it comes with a wiring kit to wire it to a modern set up but is this worth doing? I think it sounds kind of cool the way it is and wouldn't want to lose the dark tone of the 3rd setting unless I could get the same tone by rolling down the tone knob when it's wired with the modern set up.
