The Spotnicks are a Swedish instrumental group, founded in 1958 in Gothenburg, who, were very successful especially in the 1960's, with their twangy-guitar sound. They were often mentioned in the same breath as groups like the Shadows or the venture. The Spotnicks rely primarily on the characteristic guitar playing their lead guitarist Bo Winberg.
In 1963 they released "Happy Guitar"
