Bucks County Drum Company’s Patent pending Semi Solid design is a result of years of development. It rises from the dust a winner… the product of a lifetime of woodworking, love of drumming, and 11 years of fine drum building. Coupled with our exclusive E.T.S, (Enhanced Tonal System), this cutting edge format brings you all of the warmth, richness, fullness, and variety of tones found in solid wood drums. When fused to the backbone of the design, a super thin 5 ply maple exterior shell, you now have all of the strength, integrity, and consistency, expected from a standard ply drum. Finally, players can have the perfect combination; a superior sounding instrument, that has exceptional strength, is extremely user friendly, and easy to tune.
