Keystone X has the color/finish on the outside matched on the inside.

Three-ply Classic Maple core with 1/16" inner and outer plys of American Red Oak.

Keystone's 5-ply combination of a Classic Maple three-ply core between inner and outer 1/16" plys of American Red Oak creates a thin, dense shell that speaks loudly with quick, even decay. To draw further resonance from this unique hybrid, the dual 45-degree bearing edge is pulled to the center of the shell to seat perfectly into the head.
