Balu Mouthpiece Cups and Rims

We have cups from our display on Clearance! Check them out here!

In 2015, after 15 years in the horn business, we introduced our revolutionary mouthpieces. We waited until we had accumulated enough knowledge to confidently create designs that work. This was  a very tricky endeavor as there are many variables and options. We focused on three goals:

  • Options that focus on quality over quantity.
  • Finding an experienced artist who can turn our vision into reality.
  • Gaining access to high precision machines to make high quality products.

Our search led us to Tim Van Gijsegem of Maesltrom Mouthpieces, a high-end manufacturer in Belgium. He not only plays the horn, but he is an experienced manufacturer of mouthpieces. He has access to an array of exceptionally precise machines which he uses to also manufacture medical and military devices.

Once I understood the quality work he does, we got together and designed 3 cup models, with two different alloys and finishes. By simplifying the choices and focusing on quality designs, we were able to make mouthpieces accessible to many amateur and professional horn players. We world premiered our complete line of mouthpieces at IHS48 in Ithaca, NY with extraordinary success, with perhaps the most mouthpieces sold at one convention by one maker, ever!

Q: How did you even come up with the names?
A: I personally don’t like letters or numbers for sizes. I believe that having names is easier to remember and make sense. So, for our 3 different sizes: Medium, Medium-Large and Large we choose MarsVenus and Jupiter and Le MeowLe Mezzo Meow and Le Meow Meow.

Q: Why Le Meow?
A: It’s no secrets that we love kittens at our shop and when I pondered what names should the “Like A Boss” model have I posted a naming contest on Facebook. There were lots and lots of good names but one stuck out: Le MeowLe Mezzo Meow and Le Meow Meow.
