Miraphone eG was founded in 1946 after the end of WWII when 13 instrument makers, who had been expelled from the city of Grazlitz, now Kraslice in the Czech Republic, settled in the southern German town of Waldkraiburg. With very few tools, they began by only repairing instruments but within two years began manufacturing brass instruments under the Miraphone brand and are still doing so today.
Lockie’s Music in Los Ángeles was the first American dealer to import tubas into the U. S. in the early 1960s. They used a slightly different spelling of Miraphone, which was “Mirafone,” in order to distinguish their instruments from the German ones (?) We believe this practice was ended around 1990.
