Gibson 1972 solidbody catalogue. Page 4. Details of the Gibson SG Deluxe. The SG Deluxe was announced in June of 1971, and manufactured between mid 1971 and early 1972. In many ways it was a renamed and redesigned SG Standard which was dropped at the same time. By the time of the Summer NAMM show of June 1972, the Deluxe had gone and the standard was back in it's place.
Like the Standard it came equipped with two humbuckers, 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. Examine the 1970 spec Gibson SG standard for comparison.
Note that there are now three finish options listed for this guitar, the usual early 70s Cherry and Walnut, but also Natural Mahogany.
The SG Deluxe only appeared in 1971 price lists, with the final listing price (USA zone 1, November 1971) of $395.
