"I've owned several vintage Couesnon flugels and a Kanstul 1525 and the new ACB flugel more than holds its own with the very best pro horns that cost 6X as much. It has that classic Couesnon inspired flugelhorn sound with the playability and intonation of a modern Yamaha." -Ray Callender

Austin Custom Brass "Doubler's" Flugelhorn: Our #1 selling instrument!

Now comes stock with the FAB 5 ACB  mouthpiece (a HUGE upgrade over the stock piece).


We currently have all finish options in stock!   Some are in limited quantities  but we have plenty of satin lacquer, antique lacquer, and clear lacquer.





Ever wished you had a flugelhorn, but couldn’t find a great option that fit your budget?


The ACB Doubler’s flugelhorn is a high quality, professional instrument that performs above and beyond its affordable price point. This instrument was initially designed for professional players who needed to double on flugelhorn occasionally. That meant we had to focus on reliability, consistency, and of course a great sound!

But this isn’t just a great flugel for the jazz soloist or commercial musician.

The Doubler’s flugel is being used by everyone from hobbyist comeback players who just want to relax after work to full-time symphony players who only need a flugel a couple times per year. You’ll find the Doubler’s flugelhorn in British-style brass bands, big band sections, pit orchestras, church groups, and brass quintets.

You might not need a $3,000 flugelhorn, but that shouldn’t keep you from having a great playing, great sounding horn. The Doubler’s is the best value flugelhorn you can find! You will not find another inexpensive flugel with as many optimizations.

Join the thousands of players across the world who are already enjoying their ACB Doubler’s flugelhorns!

Here's a review from one of our customers (scroll down for more):

"Trent and the ACB Squad have done it again..... a 3 run Homer in the bottom of the 9th! I’ve been an ACB client since the beginning and this is my second Doubler. I can’t say enough good stuff about this horn! It has a smooth, even tone over the whole horn. Intonation is pretty good and it blends and cuts enough in a section to get over the band and It’s very comfortable going between this and my Bb. You won’t find a better horn for the price point.  Bravissimo ACB!!" - Mark Russo (3/28/19)

The ACB Doubler’s line is made by a great factory that we work with in China. The Doubler’s instruments are built to our specifications, then optimized here at our Kansas City shop before we ship them to you. The Doubler’s flugelhorn is designed to make it easy to switch between flugel and your trumpet or cornet.

We went with a 6-inch diameter bell, copper bell bow, and a classic .413-inch bore. The result is a flugel with great slotting and good  intonation, and a sound our customers describe as fat, mellow, smoky, smooth, and warm.

We align the valves on every Doubler’s flugel prior to shipment with durable synthetic pads. We also do a full ultrasonic cleaning, adjust the springs, and perform several other optimizations. Finally, each horn is play-tested to make sure that when you open the box, your new flugel is ready to go.

    Doubler Flugelhorn

    Posted by Gary J Spears on 4th Jun 2024

    Intonation is great! Love the third valve trigger but don't need it much as the horn slots and sounds great. Beautiful finish, (I choose Satin). Glad I got the Fab 5 mouthpiece for a few dollars more. Definitely a good deal!

    This horn plays beautifully and responds wonderfully. It is a great addition to anyone’s collection for any musical purpose. Jazz, concert band, orchestral, whatever you need it can do it.

    Great Instrument & Amazing Value

    Posted by Dan Kelly on 12th Mar 2024

    I really appreciate Mr. Austin's business model with his Doublers. When I found out about a line of instruments for trumpet players to get good quality secondary instruments without spending primary instrument prices, I thought "Hey, that's exactly what I'm looking for!". So about a month ago, I bought the Vintage Antique Flugelhorn with the Feb 5 mouthpiece and have really been enjoying it. The flugelhorn definitely takes more air to play than a trumpet. This takes some getting used to, but I think I'm been getting better at it. The horn has a great mellow tone that I especially love for numerous jazz ballads, Irish melodies (Danny Boy), and Beatles' songs (Yesterday). I haven't performed with it yet, but that'll come sometime after Easter. Mr. Austin, Josh, and the rest of the ACB team: thank you for creating your Doublers line of instruments and for the great customer service. I appreciate what you are doing and hope to visit your shop one day.

    I've had my Doubler's flugel for a while now and i can say with out a doubt its one of my favourite purchases of all time. Great value for the quality. I play it everyday and it always makes for a great enjoyment. Josh was fantastic with helping me with all of my questions and he answered promptly and very concise. Very reliable company and instrument.

    ACB Doubler Flugelhorn

    Posted by Leon Washington on 28th Feb 2024

    There's a reason this is the ACB's best selling horn. It's a terrific instrument! Very easy to play (right out of the box), easily tuned, very nice tone, slides and keys are very smooth. The horn works as expected, and I love playing it. I have the Vintage finish and I love the look! In fact, everyone who sees it loves the look. I really love playing it! I highly recommend it!

    Like the Doubler's Cornet I also purchased, this is my first time playing flugelhorn. It took some time getting used to it but I like it a lot (personally, I went with a mouthpiece close to the same size as my trumpet but with a deeper cup). I spent a great deal of time deciding on a finish and finally went with the Vintage Antique Lacquer and it's perfect. To me the sound is great and it more than held its own in a duet (have a trio in a few months). I highly recommend this, it's easy to see why this is a best seller.

    Really enjoying my ACB doubler flugelhorn

    Posted by Matthew Doran on 16th Dec 2023

    This horn is a great value…definitely get the ACB 5 mouthpiece bundle! This is a nice responsive horn and once I paid more attention to getting 1st and 2nd valve slides pulled out tuned it’s been difficult to put down!
