This is just a great all-round straight mute for trumpet. It could be used in any setting, orchestra, jazz combo, big band etc. The reason for this is the copper bottom; you still get that piercing straight mute tone but you can also get really dark and intimate with this thing, especially when playing softly in the lower register. There is very little resistance so playing loud/high requires no extra effort than normal. Also the tuning is not effected, at least not as much as other straight mutes. I never need to pull out my slide when using this mute. I would really recommend this mute, especially for people who might need to play in a variety of settings and only want to spend money on one straight mute!
