Gibson 1972 solidbody catalogue. Page 5. Details of the Gibson SG Pro. The SG Pro was announced in June of 1971, and manufactured between mid 1971 and mid 1972. In many ways it was a renamed and redesigned SG Special which was dropped at the same time. Like the Special it came equipped with two P90s, and vibrola, but it also underwent the changes that were being introduced in many Gibsons at the time; smaller raised pickguard (rather than full face), surrounds on humbuckers, Bigsby (rather than Maestro) vibrola, and front-routed control panel. It did get an intonatable bridge for the first time. Examine the 1970 spec Gibson SG Special for comparison.
US zone 1 price (26/6/71) for the SG Pro was $325, rising to $345 in the next price list (22/11/71).
