This is a 2011 Austin Clark 17AT Archtop Guitar. Known primarily as builder of mandolin-family instruments, Austin has also made a handful of excellent archtop guitars, one of which we have here. The 17AT is a 17" archtop, it features a hand-rubbed oil varnish and French polish sunburst finish over an x-braced Adirondack spruce top, with flame maple back and sides.
The installed floating Kent Armstrong humbucking pickup is wired directly to the output jack, with no volume or tone controls.
