 scheme similar to the diaphragms inside a speaker. The instrument was 3-4 times louder than a normal acoustic guitar and had a rich, metallic tone, as though it were being played in a large metal basin. It became known as the resophonic guitar (sometimes called National or Dobro). Joined by his brothers Rudy and Emil, as well as a group of willing investors, Dopyera founded the National String Instrument Corporation

Later years

In 1932, working together with the guitar player Art Simpson, Dopyera invented a new type of guitar design later recognized to be first ever industrially produced electrified Spanish guitar in the world. Dopyera also invented a string-gripping device on acoustic guitars, the forebear to that on all guitars today. Dopyera's later patents included resophonic additions to nearly every string instrument, continued patents for the designs of banjos and violins, including the very unique Dopera Bantar, which was a cross between the 5-string Banjo and 6-string Guitar. The Dopera Bantars, though extremely RARE were used by a few influential artists of the 1960s, including Bob Dylan. As illustrated with the Bantar, John removed the " Y " from the Dopyera name, when labeling his new instruments, as he reasoned that " Dopera " was easier for the public to understand and pronounce.

He was never rich, and was famous only among a small circle of people who knew he had invented the resonator/resophonic guitar. He died at the age of 94 in 1988, having registered some 40 patents.

Legacy

The Dobro resonator guitar was fundamental to the evolution of bluegrass music. The design cut through all musical boundaries, however, proving equally at home in folk, rock country, blues and jazz. In 1992, Slovak blues guitarist Peter Radványi co-founded the Dobrofestival in western Slovakia's Trnava
