There are so many different Bill Lawrence L-500s it is pretty confusing. I have experience with the 70s, the 80s OBLs and the new Wilde by Lawrence pickups. The commonality between them all is a rather strong midrange. I have read about a thin midrange only with the Bill Lawrence USA models - never had one of those so I cannot comment.
No idea which variety Wolf Hoffmann used but I suppose it was one of the 70s or 80s variety as he switched to EMGs rather early. I just checked Fast as a Shark and Rebel, and I guess the Rebel Yell would cop these tones quite well.
