The Gibson L9-S Ripper is a model of electric bass guitar made by Gibson Guitar Corporation. The Ripper was manufactured from 1973 until 1983, the peak year being 1976. Most had a maple body with laminated maple neck; however a significant number manufactured in 1975 had lighter alder bodies while retaining the maple neck. Also in 1975, an edgier and slimmer body, with more beveling and contours around the horns of the bass, was introduced.
