This is the bass drum made in Italy that allows children to learn sound variations by tuning the durable plastic rims to different pitches using inset lugs (allen wrench not included). The resonant fiber 12" shell uses two strong plastic drumheads that will endure hours of flams, paradiddles, and ratamacues. Includes one pair of wooden felt-tipped mallets for softer tones and one pair of plastic rubber-tipped mallets for sharper tones, all of which fit snugly into the non-toxic lamellar varnished Birchwood frame that stands upright like a true concert bass drum stand. Comes with two replacement drumheads. Ages 3 and up. 15" D x 21 3/4" W x 33 1/2" H. (12 lbs.)
