KGU TRUMPET MOUTHPIECE BOOSTER Amplifier Enhancer review video by Kurt Thompson
Folks I like to keep an open mind and try many things. If this product can help you…even 1 or 2 % it’s worth it because over time, once you add all these little extras up, it ADDS UP TO BIG IMPROVEMENT!
BTW: kurt may earn the tiniest of tiny fees should you click the link and get this, but don’t worry: Amazon takes the hit and still gives you the lowest price. How low? LOW! no taxes! no shipping
