Best Brass Nano Warm-Up Mute

Oddly enough it works exactly as advertised. I am using it with a Soulo Harmon Mute. My only complaint is that it is so small I am afraid I am going to lose it in my case or in my office so I attached a detachable key chain to it to make it easier to find.

I'm back playing trumpet after 53 years not, and I like to practice quietly so as not to disturb my wife. I have another silent mute, which works quite well, but the Nano-in-a-Harmon is way more fun!

I recommend this mute. It significantly reduces sound without any added back pressure. Added benefit is the low G and F# speak well and are in tune.

Great mute! I’ve played quieter practice mutes before, but this one plays very in tune and most others have tuning issues. Also, I don’t have to take up room in my mute bag for a practice mute. Just clip this on like a key chain.

This tiny mute is well made like all other Best Brass Mutes. It actually works very well and can be used in a "Harmon" mute directly or in the stem (at least in the stem of the Best Brass Wah-Wah and Cool Jazz mute, which is what I used it with). If using it directly in the mute, it tends to slip out due to the lubrication that is usually present to make the stem slide easily in the mute. If using it directly in the mute it would be best to clean the area from lubrication where the stem slides in so this little mute stays in place. When using it in the stem this is not an issue. Overall I liked this mute and gave it 4 instead of 5 stars just due to the slipping issue. If you need a very small mute due to available storage space or for traveling, this mute will work well for you. It's almost as good as its big sisters/brothers, the Best Brass Warm-up and Warm-Up Jr. mutes. However, if the size of the mute is not at issue, I prefer the Warm-Up and Warm-up Jr. mutes.
This mute is very small and cute and can also be hung on a key chain, bag strap, etc. (it comes with a clip/tiny lanyard for this purpose).
