I just bought a Selma 3 in 1 sax mute and a stars & stripes (regular mute) on Ebay. I put the stars and stripes in first on my alto or tenor, then I place the 3 in 1 on top. I am very pleased with the amount of volume reduction. I had tried the towel for a while, it was too much of a headache. I tried a few stuffed animals, they worked ok. Also tried the toilet paper trick someone mentioned somewhere else (LOL), not very effective. I'm very happy with what I'm using now. I'm thinking of trying the new Selma mini mute box since I like to record.
