More Info
The Tricone design uses 3 small spun aluminum cones to amplify the strings, set inside a hollow metal body of "German silver" alloy. This mellows the attack and adds sustain, creating a uniquely ethereal sound. The Tricone was a product of a collaboration between inventor John Dopyera and Hawaiian guitarist George Beauchamp, who wanted a louder instrument for the vaudeville stage than existing wooden guitars. The project came out so well that in 1927 they attracted investors and went into production, with four styles of Tricone resonators ranging from a plain deco Style 1 with no body decoration through the elaborately engraved Style 4.
