Yeah, the first Chic album (Dance, Dance, Dance. Strike Up The Band, Everybody Dance) was a P , after that it was the Stingray.
I recall an anecdote from John Taylor where he had borrowed Bernard's Stingray (possibly the first Power Station album?) and came in one day to be horrified to discover one of the studio hands, seeing how old the strings were, cut them off and restrung it. John, naturally, went ballistic.
