Overview
A fascinating hybrid stringed instrument featuring a dual-soundhole body and a complex arrangement of melody and chord strings. These 'parlor instruments' were designed to allow amateurs to play complex-sounding music with minimal training using numbered charts.
Story
In the 1890s, Oscar Menzenhauer patented this design to bring music into every home. It promised that anyone could play like a pro by following numbers. It was the 'Guitar Hero' of the Victorian era, sold by traveling salesmen.
Maker / Origin
While many were made by the US Guitar-Zither Co., the style originated with German immigrants who revolutionized the American music market. These makers focused on accessibility, creating instruments that didn't require years of formal conservatory study to enjoy.
Condition & Value
The instrument shows significant surface dust, some oxidation on the strings, and wear to the decorative decals. The presence of all tuning pins is a plus, but the lack of a tuning key and potential wood warping from age are common issues that limit top-tier pricing.
