The snare drum is the most important component in the drum set, and the snare-wire is a crucial component of your drum_s sound. This fact has not been widely recognized until very recently; only a few drummers understand this important connection. After years of careful analysis of the material composition, thickness of the end plate, shaping experiments and production consideration, we have the CANOPUS Vintage Snare Wire. 1n 1960, Ludwig and Slingerland manufactured what has now become the standard for good vintage wires. Several manufacturers have tried to re-produce the sound. After years of research, we have replicated the Slingerland wire taking several factors into account such as material, spiral diameter and pitch. We finally decided on a core thickness of 0.5 mm, a spiral diameter of 1.35mm and a pitch of 3.4 mm. After years of careful analysis of the material composition, thickness of the end plate, shaping experiments and production consideration, we have the CANOPUS Vintage Snare Wire. 2 type for your choice,DR and NP DR : Without plating - dry and crisp sound NP : Chrome Plating - reduced unwanted high pitch overtone,yet rich and mild sound (ZL : for Zelkova snare drum)
