I love this booster..... it projects my sound and gives a very nice attack to my notes!!

I’ve tried other boosters and they worked great, but this one... all I can say is WOW!!!I purchased the Heavy booster and its perfect for me

This booster is great

You should buy this if you're looking for a well-made booster that will give you instant gains

The booster improved my tone, my pitches, and the overall control of the horn in all registers

great booster

It comes in a classy wooden box that slides open to reveal a beautiful brass booster

Highly recommend this booster for trumpet players.
