The first Duolians were made as an alternative to the much more expensive Triolian as a response to the rising costs of living in the Depression. Sears, in 1931, ordered a line of Duolians to be sold in catalog, made with no logo. These guitars, oddly, often come at a premium to their labeled counterparts.

The body is made from stamped, welded steel, with a spun aluminum resonator cone. The original color was most likely a color called Duco green, but it's long since had a refinish to the blue we see here. The neck is mahogany, carved in a full 'C'-shape with a slotted headstock, and due to its catalog origins, no logo. The tailpiece is original, and a typical design for National at the time. The tuners are most likely original as well, and feature black tuning buttons, uncommon for the era but not unheard of.

With a 1 3/4 nut and an approx. 25" scale length, this resonator has a squarely vintage feel that is entirely in line with its sound.

This guitar has had a refret at some point, as well as some additional inlay added to the fretboard. The nut is bone, and most likely replaced. The cone and biscuit are original and in excellent condition.

These guitars are always killer, and this one is no exception. This example sounds and plays great, perfect for old-time or country blues, with a forward, present sound that immediately brings players back to a different time. Comes with a modern hard case.
