Introducing the Austin Custom Brass Fabrication Series Trumpet Mouthpieces!
After many clients, educators, students, and fans of ACB asked for a great introductory trumpet mouthpiece for folks on a budget, I'm extremely proud to announce the newest development in the Austin Custom Brass series of mouthpieces, the ACB Fabrication series. This is in response to overwhelmingly positive support for the ACB 5 Mouthpiece.
I now have four Fabrication Series models available!
The only reason I can sell these mouthpieces at this inexpensive price is because I order literally hundreds of them at a time. This way we don't have to compromise on quality or "cut corners" to save money. Like our Standard series mouthpieces, the Fabrication series mouthpieces are made here in the USA with the best tolerances that you can buy!
I am offering a mouthpiece I've designed for the mass population out there. Most of my line can be totally customized; the Fabrication series mouthpieces are only available in silver plate, in the unique "ACB blank" (only available in this series!) that optimizes resistance and projection to work wonderfully for the developing trumpeter.

Each mouthpiece is silver plated and features the unique "ACB" blank (mixing my ultra-light and Modern blanks) optimized for ideal response in conventional equipment.
The ACB 1.5 is similar to my ACB 1 1/2C but matched with a more efficient backbore, smaller throat and bore, and has a bit more efficiency and zip in the mouthpiece overall. This mouthpiece is great for horns and players that want to have more zip and front to their sound.

  • .668 diameter
  • Medium C bowl cup
  • 27 throat
  • Custom backbore designed just for this mouthpiece line

The ACB 3 is modeled after the ever popular 3C. It's different than my 3C as it's actually a bit bigger than my stock ACB custom 3C.

  • .656 diameter
  • Medium C bowl cup
  • 27 throat
  • Custom backbore designed just for this mouthpiece line

The ACB 5 is a unique mouthpiece and is a wonderful transition piece from the traditional student "7C" equivalent.

  • .650 inner diameter
  • Medium c/d hybrid bowl shape with blended entrance into throat (a great efficient cup shape without it being shallow)
  • 26 Throat
  • Custom medium sized backbore

The ACB LEAD is modeled after an old custom Giardinelli mouthpiece that I got in a horn purchase years ago. I really loved the feel and sound but the backbore and throat were too small for me. After digitization and messing around with a few components I think this is a WONDERFUL mouthpiece for the student who needs more zing, zip, carrying power, and efficiency. It's also very easy to transition to for most "3C-type" players.

  • .630 diameter
  • Medium shallow CV hybrid shape cup
  • 27 throat
  • Medium tight custom backbore

    ABC Fabrication mouthpiece

    Posted by Doug Wonder on 13th Aug 2023

    This is a very good commercial mouthpiece. A little too shallow for playing in concert band, where I can use my Bach 7B, but gives a lot of support in the upper range for commercial, jazz, or Big Band lead playing. I will definitely use it in my church praise band.
