It's a 1978 Gibson Les Paul Custom Electric Guitar getting a much needed Re-Fret.

These frets were played hard, have been re-dressed many times, but they have no life left in them. It's time for some new frets.
We also have to struggle with the question of whether to preserve or remove the old nibs; weighing originality verses practicality.
In this video we will talk about why the nibs are there and why many players prefer to remove them. We will remove the old frets, level the fretboard (nibs and all,) install new frets, level, dress and polish, new nut, setup and get this old beauty back on the road to singing it's soulful tunes!
