Product Overview

Austin Custom Brass Backbores

 

ACB backbores are now in stock!

All ACB tops and backbores utilize the now universally accepted "Warburton" threads, making them compatible with almost every other maker's modular components! Check out our mouthpiece sizing spreadsheet to see which backbores come standard with our various one-piece mouthpieces. If you want help choosing a backbore for your particular playing needs, please call our Mouthpiece Hotline at (781) 816-9664 and we'll be happy to assist you!

 

ACB backbores are designed to be as acoustically efficient as possible. Currently I have many different tapers available!

Standard backbores

Here are our standard backbores, from high compression commercial backbores to wide-open orchestral backbores:

  • KA3: Our newest commercial backbore and it is amazing! Feels almost like the throat is one size smaller due to the compression.
  • KA2: A very nice backbore with good zing.
  • KA1: More core than the A2 and a bit tighter as well.
  • A2: The A2 is a weapon!  Designed to be mated with compression mouthpieces. 
  • T (Tight): commercial backbore which provides the most resistance and "zing"  to your sound
  • MT (Medium Tight): Provides great resistance, especially for players who tend to "backup."
  • S (Standard): Provides the best balance between resistance and sound spread for most players. 
  • MO (Medium Open): A great slightly open symphonic shape produces a rich, warm tone but still gives ample resistance when needed.  
  • A1: This backbore is a very large, symphonic backbore that is in between the MO and O – a wonderful backbore suited for the classical player or jazz soloist wishing for a large sound!
  • O (Open): This is a very large, open backbore designed for the orchestral musician to provide the feel and sound spread that most orchestral players prefer
  • OO (Very Open): Huge backbore for enormous, rich sound (takes a lot of air)

Specialized backbores

We also have some specialized backbores that are different than the "standard" line:

  • AOS: Designed for C trumpet players looking for a large and warm sound, it's open and free-blowing. It provides a feel and sound spread that is perfect for orchestral playing and for chamber music.
  • AK: Another specialized C trumpet design, our AK backbore is a very large, symphonic backbore that is based on some of the best of Tottle designs. Used by orchestral players for decades (and very popular at one time in the BSO) the AK is an open backbore with a huge sound! 
  • KA1-3: Based on the great customer response to our A2 backbore we decided to expand our commercial backbore line with the three new options in our KA Series!
  • VNT: a vintage trumpet shank backbore specially designed to work with pre-1930's classic trumpet shanks (King liberties, Holton Revelation, Martin Handcrafts, etc), available here.

 

We also have two different cornet backbores available (one in standard length, and one in the short "British" length which works nicely with larger tops). 

  

All trumpet mouthpiece backbores can be ordered now to be cut for sleeves in the drop-down menu (the sleeves are not included in the purchase).

All backbores will be made with a #27 (.144) throat. If you would like to add a custom size we can do almost any modern  size. Let us know We'd be happy to help!

 

For Gold plate add $30 and 3-4 weeks for delivery.

    MTH backbore review

    Posted by Ron Jimison on 30th Apr 2020

    I have a TA-3 top that did not match any of my (symphonic) backbores. I discussed with Josh what I thought I needed. He asked about my playing and my setup (Schilke B1-LB). He advised this MTH backbore. I will not know for the next month (or five?) when we can play gigs again how it works in a bi room, but here in my home studio it does just what I hoped. As always, the quality is perfect, and in spite of the current situation, shipping was very fast! Thanks to all at ACB!

    Great Backbores!

    Posted by derek limback on 12th Nov 2019

    I own 4 different ACB backbores that the friendly staff at ACB helped me choose with specific tops as well. The quality is great and I have been in love with the ease and efficiency in my new equipment. I have better range now at age 45 then when I was playing all the time in my 20's. I love the flexibility that the backbores and tops offer me in different situations.

    Heavy Tight Backbore

    Posted by Harrison on 24th Aug 2018

    I wanted a heavier mouthpiece so more sound transferred into the horn and a lead mouthpiece because I play quite a bit in the upper register, Double A on a regular basis. This piece plays crisp, notes are well defines, and I cut through a 25 piece brass group that plays loud. It's a keeper!
