Needing to practice at odd times and in odd places over the years (and the absence of a suitable mute) was the reason Trevor Bremner designed the sshhmute. In development over several years in his New Plymouth workshop, the sshhmute is at long last in full commercial production and has been successfully launched to answer a market need for an effective mute in a price range to suit budding musicians and professionals alike. The traditional complaint against practice mutes has been an unnatural level of resistance that makes practice inconsistent and less helpful. That complaint has been addressed and for the most part eliminated with the sshhmute.
