19mm 13-ply Baltic Birch ply is stiffer and less resonant than a plank of solid or laminated Maple. Some drum companies offer shells fabricated from Birch (most notably the German-made Sonor, the Rolls Royce of drum companies), for a sound somewhat different than the more common alternating-Maple/Gumwood 3/4/5/6-ply shells of other drum companies
The Radio King drums of the 30’s/40’s/50’s (played by Gene Krupa) had solid Maple shells (not plywood), and are very resonant and "woody" sounding (I have two sets of 1950’s Radio Kings). There is one contemporary drum company (Craviotto. John was [R.I.P.] a Santa Cruz-based drummer who was in Neil Young’s band in the 70’s, and one lineup of Moby Grape) making 1-piece, solid Maple shells, and they are very resonant (no glue between plies---there are no plies!).
So ya’ll like the sonority Maple adds to the sound of your systems?
