Long Island Brass Company

Long Island Brass Company Custom mouthpieces made with precision to help you find your ideal sound To put it simply, we are not like the rest.

Long Island Brass Company prides itself on its unique and innovative approach to instrument manufacturing. Down to even something as simple as a ferrule, we have chosen our methods of horn building based on what will create the best product for the player. In short, this means a higher degree of precision that you will not find anywhere else. To continue down this road of unique innovation, we have also adopted the use modern manufacturing processes, by integrating custom CNC machined components standard on every horn. This gives us the ability to produce components that would otherwise be impossible to create. Most recently we have aggressively expanded into mouthpieces, utilizing our high production standards to launch our innovative designs. With each LI Brass Co mouthpiece, every player receives a specimen which exudes our industry leading quality standards. We strive to create the best possible experience for our players, so if you are unsure of the best fit, or have questions, please reach out with a quick message or send us an email.

Alright folks, you overwhelmingly asked we bring these back, so we are going to start taking orders. Unfortunately due to the extreme amount of time needed to make each one, we will be offering them in the Masterpiece Collection only, at $649 each for all sizes. Each order included a resin hybrid too and a bronze shank. Anyone who wants one should email us at [email protected] to place their order.

Remember that dented mouthpiece? We fixed it to go in our demo kit! ๐Ÿ˜‚

A question we've been getting a lot recently is what brand of trombone is in our photos? Easy, ours! Before Long Island Brass Company made mouthpieces, we predominantly produced one off bespoke custom trombones. In any field we're in not only do we innovate, we dominate!

Even in this photo of a bass trombone mid process, the list of custom touches no one else in the industry even dares to try is massive. That little gooseneck? That's a custom cnc'd part in bronze, with an internal compound curve geometry, and it's shouldered for strength externally. The part right above it? That's 3d sintered metal printed again in bronze.

That's how we do things here, not a single piece is overlooked, or considered unimportant.

It would appear we have deeply offended some people with our grotesque usage of AI. All I can say is..... GOOD.

(Note: any anti AI and negative BS will be removed and find you banned from the page, I just don't have the time to deal with this in any other way. Too many actual kind, genuine, caring customers to fill orders for, that's partially why we use AI in the first place!)

Sometimes, there's lemons. This masterpiece collection tuba mouthpiece came back from plating with a huge dent in it. No bueno. Since it doesn't change how it plays, it'll probably find a home in the demo kit, but never into a customers hands.

Here's a bronze and resin before shot. This has a bronze core and a sacrificial plate, turning into one of those beautiful mouthpieces you're all messaging us over. Don't worry! We are looking into pricing them out to bring back! (Would only be the masterpiece collection and would have a healthy premium).
