This is a spiral cymbal made by modifying a Sabian AA series ROCK CRASH 16-inch. Since the original was a hard and powerful pro-use rock crash cymbal that could be used normally, it has a wide volume range, and you can also enjoy the tonal changes of the touch. The original is discontinued, and I haven't tried it, but it has a trashy tone and a long sustain, so it seems like it could be used in interesting ways. When hung, it extends about 50 cm, and is compact and flexible in setup. This item is made by modifying a used cymbal, so there may be rust, dullness, and dirt. The cut surfaces and edges have been polished and smoothed, but please understand that this is amateur work before purchasing. If you have any questions or concerns, please comment in the comment section. Thank you for viewing.
