"Trent, you finally made me do what I never thought was possible. I've been playing the TA-1 almost exclusively for a few months, and you know what? I've actually sold all of my mouthpieces made in Portland, OR (you know the ones) and have made the TA-1 my main piece. I love the V shape, the rim, and I never thought I would love the smaller size (smaller than what I've always played), but I do. I sound better, my range has increased significantly (and not just up at the top -- my pedal tones are better too), and it just makes me happy! Great job, and thanks!" -Robert Kerr

The Trent Austin Signature Mouthpiece From Austin Custom Brass

Now you can play on the same model mouthpiece that I perform on regularly! The TA1 is a mouthpiece that I created to be my own “daily driver” for most of my work. I needed a comfortable rim and great efficiency for extended practice sessions and small group gigs, but I still wanted a rich sound with lots of character. The TA1 design gave me all that and more. It has now become one of the most popular designs in the ACB line!

It’s hard to describe this mouthpiece in full detail but I can give you a snapshot into what I designed:

I love the great vintage pieces of the 20’s-60’s from such makers as King, Heim, Al Cass, Giardinelli, Vincent Bach (NY), Parduba, and Purviance. I truly believe some of the most fantastic design concepts came out of that “golden age” of trumpet. I’ve been very lucky to acquire mouthpieces used by many of the world’s greatest trumpet players.

One of my favorites is the special mouthpiece made for one of my heroes, Clark Terry. Clark’s piece, which was based on a Gustat Heim design, had a wonderful “vee” shaped cup. It was incredibly efficient without making the tone brittle or strident. I incorporated the V-cup shape into my TA1, giving it both wonderful ease/efficiency and an incredible tone. 

While the TA1 is based on Clark Terry’s mouthpiece, I made a few alterations and improvements. Clark’s original rim design was VERY flat, so for the TA1 I modified the rim and cup to make it more accessible for today’s modern player. The TA1 rim is still flat, but not nearly as pronounced as on Clark’s mouthpiece. I increased the diameter of the piece as well, as the original was a tiny bit small for my taste. I blended the cup entrance to the throat a bit more to make the balance between cup and bore much more efficient. The TA1 also has a slightly bigger backbore to help today’s player, as many prefer slightly more open backbores to the tighter vintage designs.

Another thing you’ll notice in the pictures is my custom blank. I believe this weight distribution helps to maximize efficiency and increase the color spectrum over either the typical “Bach” style or heavy blanks.

To describe this piece in a “modern context”:

  • The rim would be like a 5-7 Bach diameter 
  • Cup is a V shape
  • #26 throat
  • Slightly more open backbore than Bach standard

Each mouthpiece will go through not only rigorous quality control but each piece will be tested personally by Trent Austin. This ensures that the equipment you are receiving will be the absolutely best quality without any compromise to “get it sold”. This is the most important aspect we can offer our clients!

Here's a customer review of the TA1:

"After a 51 year hiatus from playing I decided to take up the trumpet again. I had a lot of study and practice ahead of me. I had no idea that there was so many mouthpieces available for the artist in today’s world. In my day a mouthpiece was just another mouthpiece as far as I knew. I was having a lot of trouble with the higher registration and aching chops. Practice was hard and frustrating for me. After much research  I decided that a call to Josh at ACB was in order. I might add that it is a real treat to call a phone number a talk to a human that knows their business. We discussed my problems and with great advice I purchased a ACB -TA1 mouthpiece. I popped the TA1 on my Brasspire  trumpet (purchased from ACB also) and practiced for a while. My range was up at least an octave +, low range was much easier and the comfort was as good as it gets in my opinion... no more aching chops. I soon bought a TA1MDF mouthpiece for my flugelhorn. Same exact deal as the trumpet TA1. Now I finally feel that my practice time is making a real difference in my task at hand. I can’t tell how much of a pleasure it is to have the folks at Austin Custom Brass as my pals. My next purchase will be the Brasspire 850 flugelhorn.

Thanks, Trent and Josh for your help and expertise.

    KA 1

    Posted by Tim McGinley on 13th Aug 2010

    Trent's new KA 1 is nothing short of spectacular. The deep cup offers a full spectrum of color to the sound yet blows with ease and efficiency. From the front of the bell, the sound flows effortlessly. The design of the blank puts the weight just behind the rim allowing it to sit securely on the embouchure maintaining a great seal. The rim is one of the most comfortable I have played on. It is well defined allowing for lip engagement with just enough cushion to allow the chops a relaxed blow. If you are looking for a great all around mouthpiece with a relaxed sound and great tonal palette, heavily consider the KA 1. I eagerly await some different cup depths on this blank. It is by far one of the most comfortable and quickest respoding blanks I have played on. Well done Trent!!!
