When I wrote my original article about Eastern European guitars [Guitars of the Cold War, Vintage Guitar Magazine, January 2002], I was still in the process of researching the roots of these instruments.
In the first two installments, I had focused on Russia almost exclusively, though I did mention Jolana guitars briefly.
In 1928, Dopyera and his brothers formed a company to produce these guitars.
The names were only labels used on certain guitars by one big mother company, regardless of where they were actually built.
Dobro was eventually purchased by National, which in turn became part of the Valco company, which went bust in 1968, but that's a separate story.
The Dobro brand is currently owned by Gibson and the Dobro resonator guitar is an American classic.
Amati of Kraslice has been in the instrument-manufacturing business for over 180 years.
The company is one of the world's largest brass and woodwind manufacturers and is known especially for the quality of their saxophones.
