The Gibson SG is a solid-body electric guitar model that was introduced in 1961 (as the Gibson Les Paul) by Gibson, and remains in production today with many variations on the initial design available. The SG Standard is Gibson's best selling model of all time. The SG generally has a solid mahogany body, with a black pickguard. The 24.75" scale mahogany neck joins the body at the 22nd fret.[2] The SG's set neck is shallower than the Gibson Les Pauls. The SG features the traditional Gibson combination of two humbucker pickups or P90 pickups and a Tune-o-matic bridge assembly, wraparound bridge, (or vibrato tailpiece, depending on the model). 22 fret.
