8 string bass guitars

The 8 string bass guitar was invented by Electrical Engineer, bass player and musician, Eric Krackow, who had played with Al Kooper's early band, The Aristo-Cats, in the late fifties and early sixties. It bothered Eric that 50% of the quartet would be tied up with the guitar doubling the bass line while playing tunes like Jimi Hendrix's, "Manic Depression." Eric, finding it too awkward to play the unison octaves himself on complex songs, remembered the 12-string guitar principle and made a prototype 8 string bass from a modified four string bass. In 1967, Eric and a business partner (Steve Wittels) brought it to Sid Hack of Univox Corp. on Long Island, which company was the importer for Hagström guitars. Sid liked the idea and ordered a trial run of 500 units. The success of that test run resulted in further production and sales.
