The two things that make a tele sound like a tele - or the Les Paul's bastard cousin, is that lack of forearm and tummy reliefs (no body wood removed), and the 3 saddle bridge. Two strings per saddle = greater downward pressure against the bridge plate = better sustain and thicker tone.
If you want to really dive deep into all of what makes a Tele so freaking magical you gotta leave the basic recipe alone in my experience.
My last was a Kirn that I sold to a buddy in Jersey 10 years ago. Last I checked he was still gigging the thing. The body is 200+ year old pine salvaged from an old barn.
