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.
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!
I've been working on a new design for the trumpet backbore line to make them as acoustically efficient as possible. Currently I have many different tapers available:
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 "back-up" with very tight commercial backbores.
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.
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.
I have two special sized backbores that are different than the "standard" line:
A1: This backbore is a very large, symphonic backbore that is in between the MO and O but feels like it combines both feel and sound shapes from the two other shapes. It's a wonderful backbore suited for the classical player or jazz soloist wishing for a large sound!
A2: The A2 is a weapon! Designed to be mated with extreme compression mouthpieces, this might be the ultimate commercial backbore I've played. It works great above high C and mates with 27, and 28 tops extremely well!
We have two new for 2019 C-Trumpet backbores:
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: This 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!
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.
In addition we have some new commercial backbores available
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.

are fantastic! Love the response and the sound. Bought the S, O, MO, and MT and use them regularly!
ACB rocks! MO and O backbores shipped the next day!
Perfectly made and outstanding!
I am very happy with my purchase. It had all the qualities that I wanted in sound and ease of playing :)
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!
Fantastic quality and Trent provides a great description of each. I have the MO and S backbores that I pair with an MV3C and MV3L. I have an MT on the way as well. I like to experiment swapping them around for different sounds I like. I have used another brand of two piece system in the past and I prefer these backbores by far. Simple sub set of options to pick from depending on what you want, no guessing between a 3-4 like you have to with competing brands. I think this is huge when making an online purchase when you can’t test before buying.
Slug backbore great all-round backbore for me.And works great acrylic tops
I had trouble with my old mouthpieces, partly because the backbores were so restrictive. Trent paired his new Gen II 3S top with the T backbore and I've got a winner,
I've always had a hard time with backbores from other manufacturers. With ACB backbores, however, they just seem to work great for me. Perfect balance of resistance and color. Thanks Trent!
Just got finally dialed in with the perfect mouthpiece combination of top, blank and backbore for my A4. Fabulous!
