Gibson 1972 solidbody catalogue. Page 9. Details of the Gibson SG100. Introduced to replace the Gibson Melody Maker, this was the first and only US catalogue appearance of the SG100. It was itself replaced by the SG I a year or so later. Unusually for a single pickup SG-style guitar, the pickup is in the neck position, rather than the bridge as in the Melody Maker and Kalamazoo KG1 that preceded it, and the SG-I that followed.
For the serious student that wants responsive tone and rich appearance
The SG-100 was first listed in the June 1971 price list at $229.50 (US zone 1 26/6/71), then again in November 71 at the same price. It was not included in 1972 price lists.
