This is a DW Collectors Series 3mm thick solid copper model. The warm and impactful sound pressure of the 3mm copper, combined with the excellent 4-inch response, makes this a very easy-to-handle model. Also, all the parts are black nickel, resulting in a cohesive and great sound, both visually and sonically. It has been used for live performances and recordings, and there is some chipping of the black nickel finish on the areas where the sticks hit, but there is no damage to the snare itself that affects its use. Currently, it is equipped with a TAMA 42-strand snare wire, and the original snare wire has been removed, but it will be included and sent with the drum. In addition, there may be some scratches and other signs of use, so please understand that this is a player's condition instrument. Copper shells have become rare in recent years, and I wanted to keep this snare drum for a long time, but I am reluctantly selling it because I need money for something else. I am willing to consider a small price reduction if you are interested, so please feel free to inquire. I would be happy if you would take good care of it.
