Tom Crown Tenor Trombone Cup Alu

This is a top quality mute and the price here at Thomman is excellent.
It's very well made with large corks that are well glued in place and easily filed to tune the mute to your liking. The sound is great a little more bright than the usual H&B cardboard mutes but it's a great sound.
This thing looks like a work of art with it's polished aluminium. Not sure how well it'll stand up to knocks and bumps - but it's a mute, it'll survive!

Awesome mute. Holds its own with more expensive ones. Stays in tune through all of the range of my instrument.
