Re: NGD 1972 Les Paul Deluxe
It's hard to date early 70s deluxes with any certainty. The serial number and the pot codes (provided pots are original) are two bits of evidence that can lead to one being fairly certain of the year. Posters above are correct, not all 72s came with the embossed pickups.
That aside, sweet guitar. Hope you enjoy her for many years to come!
