Gibson RD Artist descriptions of controls (1978). These are the controls for the first version of the RD Artist bass, 1977-1978. Have a closer look at a 1978 RD Artist bass. In 1979 the controls were changed; both simplifying them and allowing both expansion/compression and bright mode simultaneously; something that can not be done on the early versions. Have a closer look at a 1981 RD Artist bass.
There are several RD Artist bass soundclips on this site demonstrating the nature of the built-in effects, and showing some of the more typical settings I use on my RDs.
