These Custom Reserve pieces are the next step in our development as a company here at ACB. They have taken a few years from concept to initial designs, to working prototypes, to this final project, and we are so excited to share these with you!
There are a couple of big points to differentiate the Custom Reserve line from our standard series:
- The O is underlined in the name for a reason: the Custom Reserve line feels incredibly open. These are designed to be played with a full air stream and as little body tension as possible. We do have a few videos to share with everyone who purchases a CR line mouthpiece to help in the acclimation process. Some will find it instantly easy to go from a standard series piece to the CR line, but even I found it a bit of an adjustment that is 100% worth the effort! The commercial pieces especially are a huge step ahead as they have such a full and rich sound while still maintaining tremendous efficiency.
- The Custom Reserve mouthpieces only come in this exclusive blank and only in brushed gold plate. We could potentially do a silver plated piece on request, but no blank substitutions. This external blank profile design is absolutely paramount to all the of the elements that make these pieces so unique. We will not be offering the Custom Reserve in acrylic or delrin at the moment due to the internal specs being too crucial to the playability of the CR line. We are working on an acrylic rim solution but still have not been happy with the results in prototyping.
- There are no alterations on these pieces because of their design. We can customize a standard series line mouthpiece if needed, but the CR pieces each have very specialized rim, cup, throat, throat length, backbore taper, and other dimensions to optimize them fully. We have spent the time really fine-tuning these!
Here's a quick comparison of the ACB 3C versus the new CR 3+ (please note I don't normally play this size but had both available at the home studio for a video):

Custom Reserve Mouthpiece Sizes:
The sizes in the Custom Reserve line are also a bit limited, based on over a decade of the most popular models we sell at ACB. Other cups can potentially be ordered but will be a 12-14 week wait most likely.
While totally revised, there are some relative comparisons between our Standard Series line and these Custom Reserve mouthpieces. If you are familiar with the rims in our Standard Series, each of these below they will feel similar on the embouchure. More detailed videos and technical information coming shortly.

Custom reserve 4+
I’m very pleased with the sound I am already getting from this new mouthpiece. Altogether refined than my previous mouthpiece I think. I have lost a bit of range but I think this will improve as I acclimate and I’ve abandoned my old piece altogether now in favour of better sound and intonation. It’s extremely comfortable and hence endurance is no problem even if surmounting some of the usual breaks is currently a bit challenging.

Austin Custom Reserve Mouthpieces
I’m not a mp hawk, hound or collector. I had been using my Schilke Tpt mp for about 25 yrs. However, being a very satisfied, loyal ambassador, of ACB, I was tempted to purchase a mp from ACB’s new Custom Reserve line. Well, as I anticipated, there was going to be an adjustment period; a time for my decades old embouchure to adapt to the new mp. Now, 3-4 months later, I’m so g as opt that I made this change. My sound is more open, in all registers, and I find it easier to reach into the high register. So, today, I’m going to purchase a second Austin Custom Reserve mp. After all, I don’t want #1 to be lonely! Incidentally, I’m playing on the L3+.

Custom reserve mouthpiece
Absolutely love the my new custom reserve mouthpiece! I thought it would take an adjustment period to play this mouthpiece, but from day one it felt great! Completely opened up my sound and a month later it just keeps getting better!! Kudos to Trent and his wonderful staff! Keep up the great work!!

ACB Custom Reserve Trumpet Mouthpiece
This has got to be one of the best mouthpieces I've ever had the privilege to perform with. I bought the 2+ model as I normally play on a 1.5C. This piece has got the richness in tone that I wanted, but also makes it more efficient for upper register playing due to the shortened length in the throat. This is a great all around piece to play on!

Custom reserve
This is really a special mouthpiece. Trent has somehow made this one of the best and most efficient mouthpieces I have ever played. Just made it through 26 Nutcrackers and loved it. I love the balance between the smaller cup, large throat and awesome backbore. Well done!!

Phenomenal mouthpiece!!!
I purchased the Custom Reserve 1.25+ and just love it. I have played it for about a month. From the very first notes, I knew this one was a winner. Solid core, easy tone production, and a rich, vibrant sound. It feels more open than my other "high end" mouthpieces and the high notes are bigger and easier with this mouthpiece. I have played a few concerts on it already and it sounds wonderful in the concert hall. Did I say I just love it????

Awesome Custom.Brass Custom Reserve Mouthpiece
I love my Custom Reserve 2 - Mouthpiece!!! It’s is a high quality piece. It rivals my much more expensive M ****** mouthpiece. Great workmanship. It plays great in all registers. Surprisingly,, I was able to become acclimated quickly. If you’re looking at Unity, make sure you check these pieces out. You may save $150.

Great piece!
I’ve been a long time ACB customer, having purchased horns and several mouthpieces from them. I was recently in need of a lead piece and was unsure about how to proceed. Josh was a big help on answering questions and I eventually settled on the TAL+ in the Custom Reserve lineup. Well this piece is everything they say it is. It produces a much easier upper register, great accuracy and flexibility, even a more robust lower register than most Lead pieces do. Plus, it’s very comfortable on the chops, and it looks great too. I highly recommend the custom Reserve line and the TAL+!!! Thanks ACB!
