The SPL Unity 5-Piece Shell Pack offers the advancing player a great sounding drum kit at an equally outstanding price. Ideal even for replacing or upgrading your existing set, they feature toneful and durable 5.6 mm, 8-ply poplar shells, which provide a live, bright sound and superior projection, very similar to birch. The 45-degree bearing edges enhance attack and creates greater sustain, resulting in a driving, modern sound. Comes complete with traditional mounts and standard lugs. Plus, SPL’s one-piece, weld-less steel hoops further enhance strength throughout.
