The GT-75 from Martin was one of the few electric guitar concepts they tested in the late '60s. Produced from 1965-1967, they obviously didn't end up sticking around, but damn were they cool concepts. Now, they are really hard to get your hands on as they were actually really well built guitars and only about 1,500 or so made.
This one is a beautiful burgundy color and has been outfitted with Lollar low-wind Imperial humbuckers that have really rad tortoise covers. There is some really beautiful checking on the finish, and some small knicks and dings as you'd expect from a 50+ year old guitar.
Playability wise? Fantastic. Decent fret life left, and setup wonderfully.
We'll get it shipped out lightning fast in its original hard shell case after purchase!
