Monster Oil Lube Master Trumpet Mouthpiece ●About the Lube Master Series The three people who founded Monster Oil are professional trumpeters. They were looking for the ultimate mouthpiece. Well, they were too. Every trumpeter is constantly searching for the perfect mouthpiece. One day he came across a BACH mouthpiece from the Mt. Vernon period. I have found the perfect mouthpiece, no wonder so many legends continue to use it. However, it took a huge amount of time and money to find that mouthpiece, mainly due to the fact that each mouthpiece is handmade and therefore has individual differences. You will also learn that mouthpieces have a finite lifespan. They struggled, but after much effort they decided to stop using the mouthpiece they had found and instead make their own mouthpiece. Aiming to create a mouthpiece for all trumpeters... The Lube Master series was created by studying dozens of BACH's Mt. Vernon era mouthpieces, which are said to be the pinnacle of trumpet mouthpieces, and blending the liquids contained in each to create a single product.・Three For users of 1-1/4C to 3C.
