660 days without playing a single concert, and then back with a new tour with several changes, the most important being Spike Edney on synths, piano and guitar. Live Aid is included here as they used Works-era equipment. Roger made a deal with Zildjian and stopped using Paiste products (including the gong).
Brian had a new replica of his guitar, made by the American company Guild (Brian was living in Los Angeles back then), which looked very similar (though not identical) and the sound was almost identical, only a bit darker. Roger, an avid guitar collector, found a classical electric guitar (which looks like an acoustic but is actually electric), that Brian would use later on for some legendary recordings including Innuendo (1989, Steve Howe played that same guitar as well).

What about the recording sessions?
The Works is perhaps the Queen album where the instruments used for the recordings differ the most from what was used on stage. On the record, they used Linn LM-2 drum machines for some songs (in fact, Roger doesn't play at all on the studio version of Break Free), Yamaha C-7 pianos (both Musicland and the Record Plant had them as part of their back-line equipment), John played the Fender Special 1981 bass on Break Free and also played three different guitars on it (Gibson Chet Atkins, Fender Telecaster and Fender Stratocaster) and the vocoder on Ga Ga was an EMS-2000.
Brian recorded Is This the World We Created with his twelve-string Ovation, not with the Gibson Chet Atkins he'd use on stage. He also used a Gibson Firebird guitar (owned by Ben Fenner) on Hammer to Fall and Tear It Up (and possibly I Go Crazy as well). That shows how Brian, even with a different guitar, still sounds like himself; on the contrary, if we gave another guitar player (even a professional one, unless they're a Brian imitator, and even then...) the Red Special and Brian's rig, he/she wouldn't sound like Brian - regardless of how important the equipment is, the main ingredient is and will always be the performer.
Synths used for this album's recordings were Oberheim OBX-a and Roland Jupiter 8.
