Did the Blackstar sport an ebony board by any chance? It looks really dark.
Black enameled maple board with micro-dots.
All SPC basses (Blackstar, Tuxedo, Redneck) had enameled maple boards, probably because maple is a dense, close-pore wood more suitable to paint over, and owners report they sound slightly brighter than standard padauk-board Rics.
4002's had ebony boards.
