Gibson Ripper circuit schematic

The original 1973 wiring plan for Gibson Ripper L9-S bass guitar, designed by Bill Lawrence. The circuit itself did not change throughout the course of production, though different potentiometers were fitted at different times. See circuit photographs | potentiometer details | description of controls

Bill Lawrence had been experimenting with LCR networks since the 1960s, resulting in the Q-filter (short for EQ filter) used on the Ripper and L6-S six string in 1973. In essence, an inductor filters midrange output, i.e. the mid control. The image to the left shows some of Bill Lawrence's early notes on the Gibson Ripper circuitry - at this stage, the mid control is named "Q-tone". Note also varitone position 1 is neck pickup alone. Production Rippers did not have such a setting (see description of controls) though some of the early prototype Rippers may well have done.

Syracuse, New York, 132**, UNITED STATES OF AMERICA

$9000

1972 Gibson L6-S Bass Prototype (Ripper, Grabber) Singlecut Sunburst
 
This bass guitar is the prototype for the L6-S bass, a model that was never manufactured by Gibson. Although it is the prototype for an instrument that was not produced, it also seems to be a prototype of the Ripper and Grabber models introduced later that are constructed with the same materials (maple neck and body) and similar dimensions. The look of this one does foreshadow those later models

Gibson L9S RIPPER 1976 Electric Guitar USA Vintage Rare Maple with Hard Case

Chesterfield, Virginia, 238**, UNITED STATES OF AMERICA

$3800

I bought this guitar around 1982. I played it in the high school marching band. It is a marvelous instrument that has always deserved a better player than myself. That being said, my only consolation in letting it go is that whoever owns it next plays the hell out it. They didn't call this model the Ripper for nothing and rock stars have long sought after this model built during this time. It sounds beautiful and it is painful for me to sell it. But I don't play it often and my home air ... more
