The earliest models built in 1962 may have featured an old-style cabinet covered in tweed. In 1963/64 a middle tone control was introduced to each channel. Although this amp was shipped through 1967, it doesn't appear that it adopted the style between 1965 and 1967 that featured black covering, a silver grille, and front white control panel.
