DescriptionOne of the problems with the new mandolin orchestras was that the mandolin family historically lacked a bass instrument. Gibson was the only company to address the problem directly. Introduced in 1912 to supply a true bass to the mandolin orchestra, the Gibson mando-bass was modeled after the Style A mandolin and tuned like a double bass. With four over-spun strings, the instrument could be played with a plectrum, unlike double basses of the period, whose plain gut upper strings required finger picking. Alternatively, Gibson catalogs also say that a small felt-covered hammer could be used to play the mando-bass, suggesting a comparison with the piano, as well as the double bass. Indeed, Gibson also stated that the mando-bass was an instrument "with a tone as deep and powerful as the bass register of a concert grand, but with the plectral tone color."
