I need to use mute everyday if I don’t want to be kick out of my house. I use it so much that there are cracks on it (!) and it doesn’t stay mounted on the trumpet all day as before, I have to put back again and again. So far I don’t feel it really destructive, but its sure not the best way to practice. I have choosen a mute with not too much resistance (wasn’t the cheaper either).
I’m interested in advices too.
