The Verithin was Hofner's thinline semi-acoustic. Gibson started producing thinlines with its ES-335 in the late 1950s; soon to be followed by a number of Gibson (Es-330, ES-345, ES-355) and Epiphone (Casino, Sheraton) variants. These were massively popular in the mid 1960s, with every major guitar manufacturer producing a similar model. Fender produced the Coronado, Hagstrom the Viking, Guild the Starfire, and Hofner the Verithin. At a time when American guitars were very expensive in Europe, the German-built Verithin was very popular with the British beat groups of the mid-1960s.
