John Abercrombie Antibes 79 

It’s a fender electric mandolin, often referred to as a “mandocaster”. There’s still people who play them, but it’s a rarity for sure!

@@kanmunson I read somewhere that he also tuned it in 4ths opposed to the normal mandolin 5ths. Really great tone, check out his sit in on the album 4x4 by McCoy Tyner. Its a face melter for sure
