New was the Chaparral Elite, which had an ebony board and boomerang inlays. Pickups were either OBL or Seymour Duncan. In 89-90, the Standard and Elite could be had with OBL Sustainiac circuitry. Sustainiac was essentially changing a neck humbucker into a high-powered magnetic E-bow, allowing unlimited feedback sustain. These later-version Chaparrals were offered until 94.
