The brand name “Teisco” was established in 1948, and sometimes incorrectly explained as[1] an acronym of Tokyo Electric Instrument and Sound Company. However, the exact name of company establishing and producing the Teisco brand was not that name, and rather, they had frequently renamed their company. The company was founded in 1946 by renowned Hawaiian and Spanish guitarist Atsuwo Kaneko and electrical engineer Doryu Matsuda. The company was originally called Aoi Onpa Kenkyujo (roughly: Hollyhock Soundwave or Electricity Laboratories). In 1956, the company name was changed to Nippon Onpa Kogyo Co., and changed to Teisco Co. in 1964. In 1967, the company was acquired by Kawai Musical Instruments Manufacturing Co. Ltd. (???????; Kawai Gakki Seisakusho), who discontinued the Teisco brand name for guitars in 1969 (1977 in Japan), but continued to use it for electronic keyboards until the 1980s. In 2017, the brand was relaunched by Singapore-based BandLab Technologies.
