Yikes, that's not the kind of slide guitar music I'd like to play. It appears to have a resonator plate like a Dobro.
A local friend who coordinates our open mics used to build them and they were pretty nice. He'd also play one on occasion during open mic. My wife found a custom builder in the little Scandinavian town just north of us, Poulsbo.
And I wish Bedifferent would post one of the videos of him playing his steel.
And Delaware Rider, very nice flooring job and nice color. It looks to be kind of a washed gray/brown. I won't show my wife those pics because I know what I would be doing next in my life.
