Äh, in meine Warmoth Tele-Body passt der Superswitch schon rein; man muß halt evtl. die Kontakte etwas vebiegen, und beim Löten drauf achen, möglichst wenig Kabel zu verwenden (und möglichst flexible Litze, und nicht starren Draht), dann läßt sich das schon reinquetschen, irgendwie...

INSTALLATION NOTE #2: SOME TELE BODIES may require you to widen the control cavity rout on the "string" side, to accommodate this wider asymmetrical switch. A dremil tool or even a wood chisel will do the trick - just be sure you don't widen the cavity at its TOP OPENING, where it would show out from under the cover plate. Will you need to widen your control cavity? StewMac.com has dimensions available on their website. Try this: envision an imaginary line that runs directly through both of your control plate screw holes on the body (this allows for misaligned control-plate mounting). The SuperSwitch, as it is asymmetrical, will require 9/16" clearance between that line and the wall of the control cavity, from 1/4" below the top of the guitar to about 1-3/8" below the top, on the side of the cavity towards the middle of the Tele (the way I have it drawn up and wire 'em) for the length of the switch (call it 1-7/8")... Does that help?
