The Ripper L-9S bass model was designed by Bill Lawrence, and manufactured from 1973 until 1983.
 
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. The later models of 1976 and on featured a different routing in the body for the wires, and the pickups were screwed in by three posts as opposed to the old two-post variation.
 
The Ripper was initially available in three colors: natural, black, and tobacco sunburst. Natural Rippers received a maple fingerboard, while black or sunburst basses received an ebony fingerboard.
 
The Ripper came equipped with two humbucking pickups designed especially for the Ripper by Bill Lawrence which were called "Super Humbuckers", and a four way pickup selector control.
There was also a fretless version of the Ripper – identical in all respects (fretboard aside) which is the model that we have here.
 
Played by a lot of celebrities such as Rick Danko (The Band), Carole Kaye, Krist Novoselic (Nirvana), Gene Simmons (Kiss), Gerald Casale (Devo), Tiran Porter (The Doobie Brothers), Peter Cetera (Chicago), Suzi Quatro, Michael Shuman (Queens of the Stone Age), Greg Lake (Emerson, Lake and Palmer), Lou Barlow (Dinosaur Jr.), Nate Mendel (Foo Fighters), Matt Sharp (Weezer), Mikey Welsh (Weezer), Mark Evans (AC/DC)
