The Gibson L-5 is an Electric Guitar used by John Mayer.
The Gibson L-5, introduced in 1923, is a hollow-body guitar designed by Lloyd Loar and produced by Gibson in Kalamazoo, Michigan. It was the first guitar to feature F-holes and became Gibson’s premier model during the big band era. Initially offered as an acoustic instrument, semi-acoustic versions were introduced in the 1940s. The L-5’s construction is similar to that of a cello, using carved and tuned woods to amplify sound through F-holes. Originally built with a 16″ lower bout, it was widened to 17″ in 1934. That year also saw the release of the larger 18″ Super 400 model.
