Dobro Dobro is a registered trademark, now owned by Gibson Guitar Corporation and used for a particular design of resonator guitar. The name was originally coined by the Dopyera brothers when they formed the Dobro Manufacturing Company to mean any resonator guitar, or specifically one with a single inverted resonator. This particular design was introduced by the Dopyeras' new company, in competition with the already patented tricone and biscuit designs owned and produced by the National String Instrument Corporation. The Dobro brand later also appeared on other instruments, notably electric lap-steel guitars and solid-body electric guitars and on other resonator instruments such as Safari resonator mandolins.

The Dobro was the third resonator guitar design by John Dopyera, the inventor of the resonator guitar, but the second to enter production. Unlike his earlier tricone design, the Dobro had a single resonator cone and it was inverted, with its concave surface facing up. The Dobro company described this as a bowl shaped resonator.

The Dobro was louder than the tricone and cheaper to produce. Cost of manufacture had, in Dopyera's opinion, priced the resonator guitar beyond the reach of many players, and his failure to convince his fellow directors at the National String Instrument Corporation to produce a single-cone version was part of his motivation for leaving.

Since National had applied for a patent on the single cone, Dopyera had to develop an alternative design, which he did by inverting the cone so that rather than having the strings rest on the apex of the cone as the National method did, they rested on a cast aluminum spider that had eight legs sitting on the perimeter of the downward-pointing cone.

Emil Dopyera manufactured Dobros from 1959 under the brand name Dopera's Original before selling the company and name to Semie Moseley, who merged it with his Mosrite guitar company and manufactured Dobros for a time. Meanwhile, in 1967, Rudy and Emil Dopyera formed the Original Musical Instrument Company (OMI) to manufacture resonator guitars, which were at first branded Hound Dog. However, in 1970, they again acquired the Dobro name, Mosrite having gone into temporary liquidation.

OMI, together with the Dobro name, was acquired by the Gibson Guitar Corporation in 1993. They renamed the company Original Acoustic Instruments and moved production to Nashville. Gibson now uses the name Dobro only for models with the inverted-cone design used originally by the Dobro Manufacturing Company. Gibson also manufactures biscuit-style single-resonator guitars, but it sells them under names such as Hound Dog and Epiphone.
