Epiphone Dobro Hound Dog Round Neck

1928 Dobro style 37 tenor guitar from Lowell Levinger's collectionThe name has a long and involved history that is interwoven with that of the resonator guitar. Originally coined by the Dopyera brothers when they formed the Dobro Manufacturing Company, in time it came to commonly mean a resonator guitar, or specifically one with a single inverted resonator. This particular design was introduced by the Dopyeras' new company, in competition to 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.
