Pearl combined four plies of Master’s grade birch with two plies of African mahogany on the interior to create the new Session Studio Select drum kits. These six-ply drums have a stronger shell, which allows them to be made at a skinny 5.4mm thickness.  The shallow 60-degree bearing edge gives punch over the top and booming lows. The kits are currently available in 6 finishes. Check out the video above for more info.
