Dobro (/doʊbroʊ/) is an American brand of resonator guitars owned by Gibson and manufactured by its subsidiary Epiphone.

[1] In mid-1929, Dopyera left the National String Instrument Corporation to start the Dobro Manufacturing Company along with his brothers Rudy and Ed, and Vic Smith.

National continued operating under Beauchamp, Barth et al.[1] Dobro is both a contraction of 'Dopyera brothers' and a word meaning 'good' in their native Slovak, but also in many other Slavic languages.

His failure to convince his fellow directors at National String Instrument Corporation to produce a single-cone version was a motivating factor for leaving.

By 1932, the Dopyera brothers had gained control of both National and Dobro, which they merged to form the National-Dobro Company.

[9] The first and second prototypes of the Dobro created by the brothers reside at the invention's birthplace of Taft, California, in a museum about the town's oil production history.

[10] On June 19, 2019, a 1933 Dobro Resonator Guitar Model 27, owned by David Gilmour was sold at auction for a record $112,500.
