Harp Guitar Larson Bas 1920

I had never seen or heard of a harp guitar until I saw this lovly one at the MFA. Apparently, they have been around for over two centuries and have a long fan list that includes the likes of Jimmy Page.

I was curious about how it sounded, so I youtubed it like anyone would. Here is a Link for you. It's a nice sounding instrument. I am sad it's not used more.
