This is a homemade violin mute. It can reduce the sound during practice. 【Features】 Not only does it provide a clear muting effect to the ear, but the effect can also be confirmed numerically through spectrum analysis. In the 1000-6000Hz range, which is the harmonic component that causes noise, the attenuation is 5-10dB, meaning the sound is less than half as loud. I always use this when practicing. ARTINO and similar products that are placed on the bridge have a high muting effect, but they have drawbacks such as: - The contact point between the bow and the strings is not visible when attached. - The fundamental tone you want to hear during practice is not audible. - Since it is only placed on the bridge, it can be dropped, or it can cause problems if left on when putting the instrument in the case. - It leaves marks or rubber stains on the bridge. - It is heavy. I made this to overcome these issues. The Quarto, which I am selling separately, could not be attached to some instruments because the parts were made larger to achieve muting. This time, the parts have been made smaller, allowing for more space up to the E string. By bringing the parts as close to the strings as possible when attaching them to the instrument, a muting effect similar to that of the larger Quarto is achieved. 【How to Attach】 Attach the two parts so that they sandwich the bridge. They are secured with strong magnets, so when attaching them to the bridge, slide the smaller part from the side to avoid impacting the bridge. Finally, move the parts up as close as possible to the E string without touching it to increase the muting effect. 【Please Note】 The height of this product (from the center of the bridge to the E string) is approximately 21mm, so it should be fine if you have a standard 4/4 violin bridge height. Some people have said they were able to use it on 1/2 or 1/4 violins, but I cannot guarantee it. In rare cases, even with a 4/4 violin, the height to the E string may not be sufficient due to the instrument's shape, so please check before ordering. Size: Approximately 42 x 21 x 5 mm. Please forgive any minor scratches from the manufacturing process. It may break if subjected to strong impact. 【From Customer Reviews】 - This is amazing!! - Unlike metal mutes, the sound became smaller as it was, which was good. - It's good to be able to practice without worrying about the mute slipping or dropping and damaging the instrument, or the anxiety of not being able to see the contact point between the strings and the bow!
