I want to put in my highest recommendation for Fabio Batanj, a luthier in Salvador, Brazil, who specializes in 5-string mandocasters (called "guitarra baiana" in Brazil). I've just had a second instrument built by him and both of them are among the best I've ever played. One is solid-body, jazzmaster shape, with 2 mini-humbuckers, while the other is semi-hollow with one mini-humbucker. If you're looking for something different and excellent, consider ordering from Fabio. He's easy to contact via Facebook listed as Luthieria Batanj Luthier.
