The Gibson Ripper has three controls: volume, midrange and tone; and a four-way rotary tone switch; unfortunately these are not marked, so players have to learn and remember what they do! The varitone positions are as follows:
Varitone position | Electronic description | Tonal description |
1 | Both pickups, in-phase, wired in series | More bite |
2 | Back pickup only | Maximum treble |
3 | Both pickups, in-phase, wired in parallel | More bottom end |
4 | Both pickups, out-of-phase, wired in series | Funky, dirty tonality |
The Ripper was designed to use all of these controls in conjunction with each other. Today, people that don't like Rippers (yes there are some!) have probably had a bad experience without really experiencing what this bass can do. But this is perhaps not surprising, especially if the pickup outputs are not balanced.. it is tempting to leave all controls on full and only change varitone positions. But this was not how Bill Lawrence designed the bass to be used. Pickup signal must be comparable for neck and bridge to get the correct out-of-phase signal. Any Ripper owner should listen to, and study the sleeve of Gibson's 1974 promo record which gives a number of examples of Ripper tones, and suggested Q-system settings to replicate them.
Because the controls for many Gibson bass instruments were not straight forward, aswell as the promo-record mentioned above, Gibson issued single-page summary sheets in 1978, detailing the precise operation of some of the more complicated models. The Ripper's is reproduced below.

The controls, as listed above, have no setting for solo neck pickup - according to Bill Lawrence's notes, this was not originally to be the case, and in many people's eyes is the one downfall of the production Ripper bass.
