Roger Waters

Roger Waters is associated with the Fender Precision Bass, likely acquired by the band around the time of the Actuel Pop and Jazz Festival in Amougies, Belgium, in October 1969. This information is detailed on Watersish.com.

He can be seen playing a Squier Standard P Bass Special - Black & Chrome Special Edition (context: https://leejameskirkham.com/p-bass-special/why.php)

The Rickenbacker Roger played was officially a Rose-Morris Model 1999, as it was a special-order for the UK importer. Released in the US under the name Rickenbacker 4001S. Its finish is known as Fireglo.

After leaving Rickenbacker Waters went through a several color combinations of P-Basses before settling on the black body and maple neck.

On the picture you can see Roger Waters posing with a Kubicki Ex Factor bass. This picture looks like one of the publicity photos made around the time of The Wall live in Berlin concert (1990), unfortunately, I haven't found any other info or any videos of him playing this bass so maybe he was just posing with it. According to Philip Kubicki - designer and manufacturer of the Ex Factor bass - he hasn't had any dealings with Roger Waters or his staff, suggesting that this bass could be a one of those made by Fender under a licence between 1988-91.

Also, Andy Fairweather Low can be seen playing a red one at The Wall in Berlin concert on Another Brick in the Wall, pt. 1 and Run Like Hell. Roger often lets members of his band use guitars and basses out of his own collection, so it's possible that Andy's Kubicki bass belonged to Roger.

Anyway, I would say that this Kubicki Ex Factor bass is a perfect match to David Gilmour's Steinberger guitar of the roughly same period, so here are some details and specs:

The Philip Kubicki Ex Factor Bass is so named because of the extended string that allows the “E” string to be “D” tuned without changing string tension or having to transpose. The patented string clasp, when released, gives access to the D# and D notes. Going from D to E is accomplished with a flick of the thumb. The standard head-mounted tuning keys were replaced by the patented body-mounted tuner. Factor basses are all fitted with proprietary humbucking pickups and circuit board. The 18 Volt circuit board has a stacked volume/pan control, a bass/treble control and a six position rotary switch that allows the player to select from a standby position through two active settings and three passive preset positions. The neck is made of 32 sheets of rotary-cut Eastern hard maple and an ebony fingerboard. The fingerboard has jumbo frets and a 7 1/2" radius.

Roger Waters has been playing several basses over his career, and without a doubt prefers Fender Precision over any other model or brand. Besides his fireglo Rickenbacker that he used for a short while before he switched to Precision, there is another bass Roger can be seen with occasionally - the black Fender American Vintage '62 Fender Jazz Bass with rosewood fingerboard and tortoise pickguard. You can see this instrument in the "protest song video" featuring Roger singing We Shall Overcome, and was also used during In the Flesh (2002) and Dark Side of the Moon (2007) tours. First (possibly) as a spare, and then by saxophonist Ian Ritchie in Another Brick in the Wall, part 2. This bass also appeared at Live Earth 2007, and the Live 8 reunion performance where Tim Renwick played it in the second half of Wish You Were Here.

The Fender American Vintage '62 Jazz Bass features the offset waist, ultra-slim fast-action "C" shape neck, stacked concentric controls, full range bi-pole pickups, and a chrome bridge and pickup covers.

The 1959 Höfner President 500/5 was Roger's first (pre-Floyd era) bass he played around 1964-65.

Today, Höfner manufactures the vintage version of the 500/5 President bass, inspired by the Höfner models of the 1950s and 60s (as played e.g. by Stuart Sutcliffe in the early days of The Beatles). With a fully hollow 16,5" wide body and fitted with close spaced original Höfner 'Black Bar' pick-ups, and with the Höfner control panel to ensure a sixties style sound.
