How about that.I thought he had an Eb3.
It is hard to say what he used, and when. The Zemaitis bass gets name checked in the credits for the 'Solid' album, and it appears on the cover of their 'Live at Leeds' album. Prior to that I've seen a couple of photos of Pete Cruickshank rocking a Fender. An EB-3 would fit his tone on 'Thank Christ for the Bomb'.
