The L-1 was introduced in 1926 and was available until 1937. This model cost $50 (equivalent to $827 in 2022). The L-1 featured a tighter grained two piece spruce top and Honduran mahogany back and sides. In some cases the back was single piece and in others it was two. Top and back were bound in ivoroid. A 2-part bridge was used in the 1928 model. In 1930 Gibson squared off the bottom to a more traditional shape as opposed to the previously "egg shaped" bottom commonly known as the Robert Johnson style.

In the early 1990s Gibson reissued the L-1 using the same specifications as the earlier version. These guitars were crafted in the Montana shop and were hand built using the same techniques as the original offering. In the late 1990s or early 2000s, Gibson introduced the L-1 Robert Johnson acoustic guitar model, the guitar features the historic small L-series body design (25" scale length), ebony bridge with carved pyramid wings, 3 3/4-inch soundhole diameter, and a Robert Johnson signature inlay at the end of the fingerboard.
