Cannot help thinking would more PUP's sound better or make stuff all difference? On Lemmy's it looks like he had 3 x Cheyenne type PUP's which appear to be a mini compact humbucker controlled by a 3 way switch and what may have been master vol & master tone.

Obviously where they are positioned will have some bearing on the sound but when considering triple humbucker LP's or SG's I have never been a fan because having three PUP's did not make them sound any better IMO.
