To me, a "classic" Tele has a thick body with no contours, bolt on neck, pickguard-mounted T-style neck pickup, and a T-style bridge pickup mounted in the bridge plate, and the top-routed electronics control plate. I'm not a vintage purist by any means, so I guess I'm fairly flexible as far as fretboard material and radius, body wood, 6 vs 3 saddles, etc. That said, my favorite guitar in the world is my Carvin TL60, which fits almost none of the "purist" requirements other than the body style neck thru construction, 5 piece neck, 24 stainless frets, 25" scale, dual humbuckers, rear-routed control cavity, no pickguard, pickup rings, neck volute, tummy contour, etc. I also have a Warmoth Thinline Tele that's a bit more traditional as far as construction, hardware, and electronics, but it has noiseless pickups, modern style truss rod adjustment, and a reverse headstock. Super sexy.
