Dobro

Dobro is an American brand of resonator guitars owned by Gibson and manufactured by its subsidiary Epiphone. The term "dobro" is also used as a generic term for any wood-bodied, single-cone resonator guitar.

The Dobro was originally a guitar manufacturing company founded by the Dopyera brothers as the Dobro Manufacturing Company. Their guitar design, with a single outward-facing resonator cone, was introduced to compete with the patented inward-facing tricone and biscuit designs produced by the National String Instrument Corporation. The Dobro name appeared on other instruments, notably electric lap steel guitars and solid body electric guitars and on other resonator instruments such as Safari resonator mandolins.
