[We've received a used Pearl Copper Shell free-floating model, one of Pearl's flagship lineups!] *There are signs of use such as scratches, stains, rust, and dents. Pearl's unique design, which eliminates all metal parts from the shell and sandwiches it between the drumhead and the lower aluminum chassis, supporting it with lug posts in a free-floating system, realistically brings out the distinctive tone of the shell. The copper model is characterized by its soft tone. Equipped with a new UltraSound snare and GlideLock strainer, it delivers a more sensitive response. 【Glide-Lock Strainer】 The strainer section is equipped with a mechanism that perfectly locks the snare wires in the ON position. Tension can be adjusted using the knob on the butt section, and the system also prevents loosening during playing. Furthermore, the internal cam ensures extremely quiet and smooth operation. The strainer and butt section can be removed from the shell along with the snare wires, allowing for easy replacement of the bottom head. Size (diameter x depth): 14 x 5 Shell: Copper Strainer (switch section/butt section): SR-1000A / SR-1000E
