I'd been wanting to learn Cuban Tres for a while and it's expensive to buy one. It turns out that the typical scale length and nut width closely match these little Mitchell travel guitars so I ended up converting one and it plays beautifully as a Tres Cubano. So I thought I'd make a few of these available affordably.
The underlying guitar is in very good lightly used condition, and comes with a solid spruce top and arched back, it's a great little travel guitar, and works perfectly as a Tres! It is excellent structurally, with appropriate neck angle and action, a ton of saddle height, and a working dual action truss rod. There are however minor cosmetic imperfections, including a couple of dings on the front as pictured.
By the way, I'm happy to do a similar conversion on your instrument, either something you already own or a model you buy new for the purpose. Not all acoustic guitars can easily accommodate the extra pins, but many can. Shoot me a message!
