John Mayer’s National Resonator 12-string

John used this guitar on rare occasions when playing the song Walt Grace’s Submarine Test, January 1967 live (something he initially avoided doing but does more often in recent years).

Here is one guitar that never did anything else but the song it was written on. I think it’s a baritone.

This National seems to be a custom-made guitar since it looks to be fairly new, and features a 12-string neck – which seems to be very rare on these guitars. Next to that, the guitar is also equipped with a sound system, which is obviously not something you’ll find on a true vintage Style-O. Beyond this, not much is known about the guitar at this moment.
