An electric guitar manufactured by Gibson guitars. Originally designed as a budget alternative to the Gibson Les Paul, and is still very similar to it in sound and construction, and, unfortunately, price.

The Gibson SG is a double cutaway guitar with a set neck construction and a 24.5 inch scale length, like the Les Paul. The guitar features two humbuckers, and a toggle switch which can select a neck, combined or bridge pickup. This distinguishes it from the similar Les Paul Jr. and the Gibson SG Jr. which typically have one P-90 pickup or something else. The guitar is constructed out of mahogany, with a maple top and rosewood fretboard. It is very thin and doesn't weigh much. It has a fixed bridge design.

The Gibson SG is favoured for its sustain, its midrange tone and its striking (for a Gibson) appearance.
