This Mars 4-piece Bop shell pack emits buttery, classic tone transmitted through beautifully finished maple shells appointed with the SONIClear bearing edge. This allows the drum head to sit flat, producing excellent response and a wide tuning range by optimizing the relationship between head and shell. This 4-piece maple shell pack comes with a 18"x14" bass drum with mount, a 10"x7" tom, 14"x12" floor tom with three floor tom legs, a 14"x5.5" matching snare, a tom holder and a bass drum lift.
