In 1967 Rudy and Emile Dopyera founded the company Original Musical Instrument Company (OMI) to produce resonator guitars under the Hound Dog brand. In 1970, the brothers bought back the Dobro brand after Mosrite, which then owned the brand, was put into temporary liquidation.
OMI was purchased by Gibson Guitar Corporation in 1993, whereby Gibson began defending the exclusive right to use the designation Dobro - which over the years has become a generic designation for resonator guitars regardless of manufacturer. Gibson has since produced several different models of resonator guitars under the designations Dobro, Hound Dog and also via its budget brand Epiphone. All of these Gibson models have a single resonator cone and are available with a round or square neck profile.
