This is a 1970’s Gibson Les Paul Deluxe with a “pancake” body made from two slabs of mahogany sandwiching a thin slab of maple. It was left in for a re-fret and a new bone saddle. The frets were worn right down, it was unplayable. The guitar had received as many fret levels as was possible. With frets this low a new nut is inevitable and there was no issue of loosing the fret nibs as they were practically gone.
