Instruments previously built in Chicago, IL during the early to mid-1960s.
The Zorko trademark is the brand name of the Dopyera Brothers (See Dobro and Valco), and was used to market an electric pickup-equipped upright "mini-bass." In 1962, Everett Hull from Ampeg acquired the rights to the design. Hull improved the design, and Jess Oliver devised a new ‘diaphragm-style’ pickup. The Ampeg company then marketed the model as the "Baby Bass." Source: Tony Bacon and Barry Moorhouse, The Bass Book.
