Oval Hole 7-string Archtop. Sitka spruce top, curly maple body and neck, ebony fretboard and bridge, aluminum tailpiece with ebony veneer, boxwood binding. The only brace is a single spruce bar underneath the bridge, parallel to it, and extending about 1.5" past the ends. The bridge is quite low, only about 1/2" high in the center, which produces a very low break angle of the strings over the bridge, and hence relatively low downward pressure on the top. I wound the pickup to Johnny Smith specs.
