1961 Les Paul SG
In 1960, Gibson experienced a decline in electric guitar sales due to their high prices and strong competition from Fender’s comparable but much lighter double-cutaway design: The Stratocaster. In response, Gibson modified the Les Paul line. This 1961 issue Les Paul guitar was thinner and much lighter than the earlier models, with two sharply pointed cut-aways and a vibrato system. However, the redesign was done without Les Paul’s knowledge. When the musician saw the guitar, he asked Gibson to remove his name from the instrument and parted ways with the company. Although this separation occurred in 1960, Gibson had a surplus stock of “Les Paul” logos and truss rod covers, and so continued to use the Les Paul name until 1963. At that point, the SG guitar’s name was finally changed to “SG”, which stood simply for Solid Guitar. In addition to the SG line, Gibson continued to issue the less expensive Jr’s and Specials (and the Melody Makers) with the newer body style. These were the standard Gibson electric models until the reintroduction of the Les Paul Standard Goldtop and the Les Paul Custom guitars to the market in 1968.[23]
