Steve Clark used a limited production 1976 Gibson Firebird, as seen in photo 8 on Steveclarkguitar's "Steve's Hysteria Tour Guitars" page. This model features a Kahler #2200B tremolo and a distinctive red, white, and blue Firebird logo with stars and a "76" on the scratch plate, distinguishing it from vintage Firebird III designs. Notably, this guitar lacks fingerboard binding and has "Limited Edition" stamped on the back of the headstock, with a serial number starting with "00" if produced in 1976.

Tom used a Firebird III during the 80’s.

Alex Chilton is pictured on the back cover of Big Star compilation Nobody Can Dance with a Gibson Firebird III, during their performance at the Overton Park Shell in Memphis, TN in May 1974. He also possibly used it on Radio City. Occasional Big Star collaborator Van Duren believes it was borrowed by Chilton after the band's equipment was stolen in 1974.

Seen played on love on tour with Harry Styles.

Marco Pirroni, the guitarist, uses the Gibson Firebird III, as confirmed in an interview with Guitar World where he mentions, "I bought a couple of old Firebirds, one of which I had painted red."
