The Regal Octofone


The Regal Octofone (or Octophone) was an attempt by the Regal Musical Instruments company to design a unique instrument that could replicate the sounds of 8 other instruments. Those instruments were the tenor guitar, tenor banjo, ukulele, taro patch, tiple, mandolin, mandola and mandocello [1]. I strung mine up and tuned it like an octave mandolin which is one of the more common ways to play these instruments. 

The shape is curious, it has two points and looks like a double cut away mandolin

The No.25 Octofone has a birch neck, back, and sides finished in a dark lacquer to mimic more expensive woods. It is ladder braced with a dowel rod neck joint. The fretboard is ebonized maple with 3 pearl position dots. The tailpiece is stamped "Bell Brand Patented NMS Co”


The No.26 Octofone features mahogany instead of birch. These are much, much more rare.

These instruments were first released (and patented) in 1928 with the patent approval coming later in 1931 [2]

President of Regal Instruments and Inventor Frank Kordick was behind the design of this peculiar instrument.
