The B-52's – Mesopotamia

Ricky's playing a Telescaster on "Mesopotamia" here (around 11:00)

Ricky had at least 3 Telecasters...seems these were used in DADxBB the most often. He started using them starting with Mesopotamia it seems.

Here's the B-52's with "Give Me Back My Man" live in 1982 on the Mesopotamia tour with Ricky on a Stratocaster (probably the same from the original source).

To add more details. Starting around the tour for Mesopotamia in 1981-1982, Ricky started using a black Fender Stratocaster a lot. This may be the same guitar also used by Keith Strickland later (ie, the one seen in the "Love Shack" video). Ricky used this guitar in many different tunings or may have had multiple Stratocasters. It appears this one is a vintage pre-CBS model going off the small headstock and maple neck, possibly late 1950's. You can tell when Ricky plays it because it's got a much more airy, modulating, and pingy sound than his other guitars. It's also possible his sister Cindy ALSO used this guitar for "There's a Moon in the Sky" and Kate used it for "52 Girls" as well on this tour. May be the communal B-52's guitar. not much of that is known.

In the video he's in DADxBB tuning. He also may have had one in BADXG#C# tuning for Party out of Bounds and Quiche Lorraine as well. Ricky continued to use the Strat right up until he passed on, and apparently Keith may have started using it on Cosmic Thing onward.

During the Meso-America tour in 1982, Kate switched from using her Farfisa organ and her separate synth bass to using the Jupiter-8 to reproduce the bass and organ parts simultaneously, as well as the more advanced sounds from the Mesopotamia EP, on one sophisticated keyboard. During the Whammy! tour from 1983-1985, she shared this instrument with fellow band member Keith Strickland, who on some songs would come down from the drum kit to play guitars and bass and synth parts on this instrument while drum machines from the Whammy! songs played, allowing Kate to focus on vocals and simple choreography.

In a comment on her page showcasing her Farfisa organ, Kate mentioned that Keith now has the instrument. Keith mentioned on a comment on his Facebook post that he has had it retrofitted with MIDI and uses it as a sound source for his compositions.

Kate Pierson's Korg Synthe-Bass was one of the keyboards that shaped the sound of the B-52's' early work. Kate's Synthe-Bass would sit on top of one of her combo organs, and she would use it to play basslines. Kate used the Synthe-Bass from 1978-1980, and it was played on the albums "The B-52's" and "Wild Planet". It can be seen throughout the linked video on top of Kate's Yamaha YC-30.

Sometime during the recording sessions for their 1982 EP "Mesopotamia", the B-52's acquired a Roland Jupiter-8 synthesizer. The Jupiter-8 became Kate's main keyboard, and thus the duties of the Synthe-Bass and organ were passed down to it. However, the B-52's did not stop using the Synthe-Bass.

During live performances from 1982-1985, the Synthe-Bass was moved to stage right and only used whenever bass parts needed to be doubled for whatever reason; it was used in this manner by Cindy Wilson on "Private Idaho" and Fred Schneider on "Give Me Back My Man".

The Synthe-Bass also appeared the music video for "Legal Tender" in 1983.
