During the mid to late 1960's a Spectrum 5 guitar could bought off the shelf for $89 or less in stores in my area. The Spectrum 5's I saw back then in my area had ebony fretboards and either had no badge on the headstock or they had the Teisco crown badge. The last new one I saw in the early 1970's had a $45 price tag on it. The Spectrum 5 was the "Cadillac" of Teisco guitars. According the trademark owned by WMI Corp. (U.S. distributor) the Spectrum name was used in the United States for the first time in commerce on July 7, 1966.
Some Teisco History from North Carolina
Between 1965 and late 1977, Teisco guitars and amplifiers could be purchased new in North Carolina stores. Among the stores carrying Teisco products were Lowe's, Rose's, KMart, Belk, Walgreens and Sky City. Teisco items could also be found in other stores that sold tv's, appliances and hardware.
