Intro video → https://youtu.be/OVpkR15p4Rs A snare drum that allows you to switch between two types of bearing edge shapes on the batter side, providing two sounds in one drum! The shell is a maple x aluminum x maple hybrid. Retail price is around 140,000 yen. I bought it for experimental purposes to try out the sound changes, so I haven't taken it outside, and it's in near-new condition except for the heads. By removing the heads, the shell splits, and by flipping the upper shell, you can switch between "double 45° edge" and "round edge". This is an innovative snare drum where you can experience two sounds in one drum. ■ Double 45° Edge Clear and modern tone. Suitable for high pitches (e.g., wind orchestra, hard rock). ■ Round Edge Soft, vintage tone. Produces a solid low pitch (e.g., pop, jazz).
