National guitars first hit the scene in the late 1920s; built to be louder than anything else on stage, they were the original solution to pre-amplification volume problems. Designed by George Beauchamp and the Dopyera brothers, Nationals introduced the resonator guitar to the world—instantly recognizable by their metal bodies and cone-driven volume. The early ones were raw, loud, and full of character; perfect for blues, Hawaiian, and early country. Today’s Nationals keep that heritage intact while cleaning up the build quality and consistency, and the Delphi is a solid example of that blend.

This mid 1990’s example, a powered coated Blue Delphi has the classic 12-fret, single-cone setup with a steel body and that unmistakable “ribbed sieve-hole” coverplate, just like the pre-war originals. Finished in a powder-coated blue that’s equal parts cool and durable, with a hard rock maple neck and ebony fingerboard that’s bound in cream and dotted with simple position markers. The slotted headstock wears the traditional National shield logo; tuners are the classic three-on-a-plate style.

Specs-wise, it’s got a 16" fingerboard radius, 1 13/16" nut width, and a 25" scale; V-shaped neck profile and a biscuit bridge over a single cone. No pickup installed; just pure, punchy mechanical tone. It’s in excellent condition for its age—light playwear on the body and neck, but no abuse.

Comes with the original hardshell case.
