You are correct about the lawsuit, I say lose as I am sure he would have preferred to pay nothing at all rather than a licensing fee! As Spector was technically Kramer and he only owed Spector a few, then no he need not pay.
So far as the clone thing goes, my personal view is I think it’s overly harsh on most bass makers out there. Someone (Leo Fender) designed and ergonomically useful and aesthetically pleasing shape to an electric bass. If It so happens that other brands can make something just as good if not better in a similar style (mostly because of our conservative nature in trying/buying products) then I feel it’s unfair to try demonise them from the outset as a ‘clone’ which is oft used in a slightly derogatory fashion. Within the ‘same design’ there is huge variation to keep people happy
They may do it in the Violin world with Amati and Stradivari etc, but that was the point being made that the violin as an example has barely changed its design.
Personally I think a Warwick looks like a child’s drawing of a melted candle with a chubby crayon, but that’s cool, they can sound wicked and Norwood fisher one of my fave bassists used/uses one.
The main concern from most, which is justified historically, is HPW taking something and making it worse as well as an unpleasant marketing strategy-some May call it clever business but he is not someone I would get into bed with.
Time will tell
