Maximum muting and clearest tone. Ideal for practicing in apartments of late at night (especially for difficult passages!) Best quality chrome-plated machine brass.All string players must have no less than one mute, and there are three important factors to believe. First and foremost, ease of use. How quickly can the mute be put in place or removed? How important is this to you? Orchestral players every so often only have one measure to install or remove a mute. Secondly, sound quality. The goal of the mute is to lower the volume only, not dampen the good quality of your instrument. Regarding overall sound quality, the degree to which a mute “rattles” when not in use but still on the strings between the bridge and tailpiece is very important as well. Third is aesthetics. Truth be told, many players believe the importance of overall feel and appear, trying a number of mutes to find out what works and looks best on their instrument. Fortunately, mutes don’t seem to be too expensive, so this can be a moderately low cost endeavor.
