"Bill: Oh I play a Seven Series Gibson Les Paul Custom and Fender EVH heads for amps. Pretty basic, really. I just love the thick sound of Les Pauls."

In this article on Marshall's website it is stated that Bill Steer used the 30th Anniversary Series Amp.

With its unforgettable look and amazing sound, this amp soon found its way onto the backline of artists such as Joe Satriani, Bill Steer (Carcass) and Alex Lifeson (Rush)....

Mentioned by drummer Mick Harris. He used it on 100% on the Peel sessions and probably on the FETO album and tour.

In this Facebook post by Jim Dunlop Products shows a photo of Bill Steer with his pedalboard.

He actually used a Strategy guitar not a PEAVEY NITRO.

Bill used Ibanez guitars throughout the carcass period in the 1990s.

Not sure what Iceman model it was but he used it before his Schechter Strategy,probably was used on the B side of Napalm Death' Scum.

Used in Carcass around 2008.
