Custom Made KGU Brass Trumpet Mouthpiece Booster - Antique Copper Lacquer Finish | Professional Trumpet Accessory for Jazz, Classical & Marching Band Performances

Wow! This booster is great! Well, I received it today. It's both beautiful and functional. I'm trying it out on a horn and setup I use for lead playing as well as a soprano bugle in G I use in a drum and bugle corps.I'm a professional trumpeter in NYC and am usually skeptical about things that may appear to be gimkicky, BUT:Both horns already slot quite well, from low to high - and they get a great sound, but adding this has given me even more of the following:- a bit more meaty core to my sound, even up extremely high in my range. My sound has opened up even more, without sounding dull and its easier to play. There is not too much Mass on the booster, so I still have rich overtones, coupled with a very robust sound!- slotting is even more secure. I can also play lip trills even easier than before with the same setup. This means less chips, bumps or unstable notes. Whew!- articulation is easier, more clear and the tone speaks easier. Articulation is of great importance when playing the trumpet!- dynamic range has been increased with more security knowing notes won't cut off at fortissimo levels and beyond. I can easily play from very quiet to very loud levels with more security and confidence.- overall improved, instantaneous playing ability! That's a huge plus for me!I'm not too big on a lot of equipment/mouthpiece/horn changes, but if it gives me instantaneous gains on a very difficult instrument, I'm all for it!I can honestly say I'm happy with this booster and it's a definite keeper. I'm going to recommend this high-quality product to my ? playing friends! You should buy this if you're looking for a well-made booster that will give you instant gains! It's worth it and then some!
