History of the Dobro from Gibson Musical Instruments

The Dobro® Story
It started out as a search for a louder guitar - a guitar to stand up to the trumpets, saxophones and banjos that dominated popular music in the 1920s. George Beauchamp, a Los Angeles guitarist, took his vision of a mechanically amplified instrument to John Dopyera and his brother Rudy, Slovakian immigrants who had already patented several improvements for banjos. John Dopyera perfected a design utilizing three aluminum cones, Rudy suggested a metal body to enhance amplification, and the National tri-cone resonator guitar debuted in 1927.

John Dopyera left National in 1928 and began developing a more affordable wood body guitar with a single cone and a spider-like bridge base. He introduced his new invention by the end of 1928 under the name DOBRO® - a combination of Dopyera and Brothers (brothers John, Rudy, Emile, Robert and Louis would play various roles in the production and financing of the company).

National responded with its own single-cone guitar, featuring a biscuit like bridge base. After each side sued the other, they merged in 1932 to form the National - Dobro company. Although resonator guitars were initially well received, the company quickly shifted its focus to the emerging electric guitar.

National made no DOBRO® guitars after World War II, but several of the Dopyera brothers revived the spider-bridge resonator guitars under the DB Original brand. Family members formed the Original Musical Instrument company in 1967 and made resonator guitars under the Hound Dog brand until 1970, when they finally reacquired the DOBRO¨ name.

Gibson Musical Instruments acquired O.M.I. in 1993, and since then O.M.I. has brought together all the best qualities of the original wood body and metal body resonator instruments, plus new models designed for slide guitar playing, into a modern line that offers a DOBRO® guitar or bass for every musical style and taste.

Today's DOBRO® guitars produce a wide range of sounds, depending on their body style and resonator type:

Three-ply wood - maple is standard but mahogany, walnut and other exotic woods are used for custom instruments - recreates the original DOBRO® sound. Painted steel produces a crisp, cutting tone. Chrome-plated bell brass emits a sweet, ringing sound.

The original DOBRO® spider bridge rests on the edge of a 10 1/2" cone, with the cone opening toward the top of the guitar. The biscuit bridge sits on the peak of a 10 1/2" or 9 1/2" cone, with the cone opening toward the back of the guitar.

Today's DOBRO® guitars reflect the preferences of working musicians for those combinations of features that look and sound best. The square neck wood bodies (60 series) typically have screen holes, while the round neck models have f-holes. Square necks have the spider bridge, while bottlenecks (90 series) have the biscuit bridge with a 9 1/2" cone and models with a radius fingerboard (33 series and engraved series) have the biscuit bridge with 10 1/2" cone.

Whether the music is blues, Hawaiian, country, bluegrass, or a style of the future, DOBRO® guitars have the right sound.
