Thanks to you, it's a big hit! Your drums will have a richer sound! Thank you for viewing. This is an original bolt rod washer set, unplated, 20 pieces per set. The washers are cast without burrs, with chamfered inner and outer circumferences, a glossy finish on one side, and a hairline finish on the other. You can choose the anti-loosening effect by changing the direction of installation. They can be used not only on snare drums, but also on tom-toms, floor toms, and bass drums. Here are some typical comments from users who have purchased them: ① The sound quality has improved, with better clarity and sharpness. ② Overtones have become pleasant, and the snare drum itself resonates more. ③ Beautiful high frequencies have been added, resulting in a usable sound. ④ The washers themselves have a high density and mass, which has a positive impact on the sound. ⑤ The sound of open & closed rimshots is pleasing. ⑥ Due to the material's characteristics, the tension bolts are less likely to loosen even with hard hits. ⑦ Compared to brass washers released by multiple manufacturers in the past, these are the best made. ⑧ It's great that they also fit Sonor's minus-head bolt rods. Brass has excellent acoustic properties and is one of the representative materials for wind instruments and percussion instruments. Looking at snare drums, one reason why vintage instruments like 60s Super Ludwigs and Radio Kings are favored is the influence on the sound due to the use of brass hoops and washers. If you are not satisfied with the sound of your drums, this is a more affordable way than replacing the hoops, and you can definitely feel the change. Please note that we are unable to accept requests for price reductions due to rising prices and raw material costs. Just washers, but they make a difference... Experience the sound that sets you apart from other drummers with your own ears. Thank you.
