I bought what was supposed to be a sax mute, for quiet practising, but it doesn't work. It's similar to a trumpet mute, which fits in the bell end. It seems that a lot of sound would emanate from the bell, because that's where one attaches a mic to amplify a sax. Saying to me that a lot of the sound actually does come out of the bell!
We have a question on how to mute a Sax, but where is the best place to fix a mic - is it at the bell?
