Although not lawsuit: I would never think of replacing the pickups of my 84 Aria ProII RSB standard.
Lovely basses. Not the P clones the OP is asking about though.Another one worth mentioning, I had an early 70s Ibanez Les Paul bass that was a beauty with some personality.
Black, mop blocks and white binding, bolt-on neck. Heavy as fu*k but played like butter and sounded really tasty live.
