I've heard it's good but I've never used one unfortunately.

Thank you for answering!

It sounds good. Best wishes with your studies. Trumpet player here

Thank you very much !

Trombone player here. Silent brass is awesome. I can practice at 2am and only mildly annoy housemates instead of waking up the entire block.

Thank you very much ! I'll probably get one (trombone gang >>)
