Thinline teles and chambered Les Pauls are made pretty much the same way with varying amounts of wood removed.

On my Vintage Mahogany LP Studio (chambered) you can follow the side grain through the carved top which leads me to think that the top and back were cut from one mahogany blank sliced through, the back thicknessed and routed for chambers, the top thicknessed and carved and finally stuck back together. It's one piece too .
