Gibson L-5 The Gibson L-5 was the first true archtop guitar, designed by Llyod Loar. The L-5 was inspired by violin construction. A pair of f-shaped holes on its arched top replaced the single round soundhole. Eventually, all future archtops were shaped like this. The L-5's sound was favored by many musicians, particularly jazz and country guitarists. This guitar has banjo tuning pegs on the other side of its headstock, with a beautifully made maple neck and varnish work.
