In this video I'm showing how you can use typical Gilmour pedals to simulate his rotary sounds.
David Gilmour has used several rotating speaker cabinets over the years, including a Yamaha RA200 during the Animals/Wall era in the late 70s and early 80s.
David Gilmour would always mix his rotary cabinets lower than the dry Hiwatt amps to create a subtle modulated tone.
I'm using a MXR Custom Shop '74 reissue Phase 90 and a Mooer ElecLady to simulate that liquidy warble heard on the Is There Anybody Out There - The Wall live 1980-81 album release.
Guitar - Fender Stratocaster, with D Allen Voodoo 69 neck and middle pickups and Seymour Duncan SSL5 bridge pickup
Amp - Reeves Custom 50, Laney LT212 cabinet with Celestion V30 speakers
Mic - Sennheiser e906
