I've been looking at a lot of used drums lately and I'm honing in on a PDP CX kit. I'm trying to determine if it has the maple shells that so many have raved about. Were all CX shells maple or were there other CX shells that were not made of maple? All I have to go on is the Blue Onyx wrap and a serial number from one of the toms. 309505. I googled it but nothing came up. Anyone with some knowledge on these would be phenomenal. Thanks.
