Since the inception of Pearl Percussion’s Elite Series of Congas and Bongos, the drums have been offered with 100% aged Thai Oak or Fiberglass shells. Now the Elite Series offers a combination of the two shell materials blended together. The Elite Series Wood-Fiber shells deliver the best of both worlds; the superior cut and projection of Fiberglass, warmed by the rich Thai Oak outer shell. Matching bongos are also available but sold separately. The Elite Series Wood-Fiber drums feature premium natural skin heads, polished Contour Crown rims and Pearl’s exclusive Self-Aligning Washer System that isolates the tension hooks from the inner walls of the lugs for greater tuning ease.
