Here is some info on the Roger Waters basses from Wikipedia ... I don't think this is completely accurate ...
Bass guitars
Höfner bass guitar. His first bass.
Rickenbacker RM-1999 (also known as 4001S). Fireglo with rosewood fretboard. Used between 1966-1969. Lost in 1970 after equipment van was stolen in New Orleans, and everything was subsequently recovered except the guitars and basses.
Fender Precision Bass. Waters was first seen in 1968 with a Precision. After 1970 he has rarely used any other bass guitars.
Sunburst with rosewood fretboard and brown tortoise pickguard. First seen in September 1968. Also used in the early 70's. Pickup cover and thumbrest (below pickups) attached.
White with brown tortoise pickguard and rosewood fretboard. Appears on back cover of Ummagumma 1969. Seen used at the KQED TV recording April 1970 as well as several photographs from 1969. Stolen along with Rickenbacker after equipment van heist in 1970
Multi-coloured jazz bass with rosewood fretboard. Actual colours of bass are unknown since only black and white footage/photos exist. This is a WWII German camouflage pattern. Used extremely rarely in 1969.
Black with rosewood fretboard. Seen in some early performances.
Black with white pickguard, maple fretboard. First seen at a concert in Hyde park in July 1970, this guitar was used on very few occasions before April 1972 when it became his de facto only guitar on stage. Circa 1976 Phil Taylor (David Gilmour's guitar technician) replaced the white pickguard with a black, something clearly visible on In the Flesh and The Wall tours. During the Wall sessions and tour Waters had three of them.
Sunburst with maple fretboard and gold anodized pickguard. Used during the Dark Side of the Moon recordings.
Black with maple fretboard and black pickguard. His main bass guitars during the 1980s solo album and tours.
Waters currently uses Samson wireless systems with his basses.
