You may have seen this but there’s a Frontline catalogue/supplement in stores now that lists the following about the Andy Summers Tele:
* Ferocious humbucking pickup
* Bridge pickup mounted in body
* Control plate mounted mini-toggle phase switch
* Body mounted premap on/off mini-toggle switch
* Rear mounted overdrive unit controlled by a third knob
* Soft brass bridge pieces
can’t help ya with the mod parts but that, I guess, is what distinguishes it from yer regular Tele!
