Collings Guitars

This is an Austin, Texas, high end Guitar manufacturing company founded in 1989 by luthier Bill Collings. They added Mandolins to the catalogue in 1999 and Ukuleles in the late 2000's. 

They make a couple of ranges of Ukulele, but only Concert or Tenor scales; unless you go for a custom Ukulele, and they do a lot of custom work
