Stroh Violin
The nondirectional sound of the violin family was difficult to capture before the advent of electric recording. Strohviols are not electric instruments, but their large funnels directed the sound of their strings toward the horn of the recording phonograph. Although electric recording made strohviols obsolete, their minimalist bodies inspired the design of later electric violins.
(John Matthias) Augustus Stroh (1828-1914) invented this instrument between 1899-1901. Charles Stroh, his son, and later George Evans produced these instruments.
