Drum Workshop has become synonymous with custom exotic finishes, while at the same time, PDP Concept Series™ drums have provided drummers with the user-friendly features and build-quality that had previously been reserved for much more expensive boutique sets. New Concept Maple Exotics deliver on both of these promises in a big way. The 7-ply all-maple shells are finished in a rich Walnut veneer with glossy Charcoal Burst lacquer. Add-on Floor Toms available in 12x14 in. and 16x18 in.
