This is a Liberty Guitars prototype that I picked up a few years ago. It's a solid brass top without a resonator. It's a pretty cool sound. I'm playing it with a capo at the 5th fret, using a flatpick.
This is an E harp into a Shure Green Bullet through a Crate Taxi. No tubes, just some overdrive. You can hear my daughter yelling "too loud!" at the end...
