ACB is proud to offer the newest addition to our Doubler's line, a fully compensating Bb euphonium suitable for serious students and musical professionals alike!

As with all of our high brass Doubler's instruments the Doubler's Euphonium is built to our specifications, then optimized here at ACB and play-tested before we ship it to you. 

The Doubler's Euphonium features a fully compensating system to help you play in tune more easily. The instrument has a yellow brass body and a 12" yellow brass bell for great projection and a full, warm, dark sound that still has plenty of clarity.

The euphonium comes with a stock, non-ACB mouthpiece.


Here's a video of the great Dave Werden playing it!

Another great feature of this horn is the case: a high quality hard case with wheels! The case is well built and sturdy, providing excellent protection for the instrument in all settings.


  • Key: Bb
  • Bell Size: 12 inches
  • Yellow Brass Bell 
  • Valves: 4 bottom sprung piston valves
  • Large .580  bore  and large shank taper

  • Instrument Weight: 10lb

    Great horn!

    Posted by Eric Carter on 26th May 2022

    This euphonium is my third purchase of an ACB doubler’s instrument, having previously purchased the doubler’s cornet and flugelhorn. I’m very delighted and impressed with the doubler’s euphonium. The sound and intonation are both very good, and it looks good too. The valves and slides are all nice and smooth, and the case is quite nice. I’m very satisfied with the doubler’s euphonium, and I highly recommend this instrument. I’m a casual brass hobbyist, and the ACB doubler’s horns are a perfect match to my interest and budget.

    Doubler Euphonium w/hard case

    Posted by Joe Mintel on 17th Apr 2021

    Excellent Customer Service. Trent Austin responded directly to me via email about shipping /delivery... I could not hide my anxious anticipation of a new Euphonium in the house! My last NEW horn was when I was in High School....We just had our 50th class reunion last fall, so that should explain my anxious feeling! The horn is the best thing since sliced bread. Am having a ball trying to get my chops into shape and have already joined a community band- doing Zoom rehearsals every Monday night. Three concerts are scheduled for Aug...if Covid rules don't get in the way. Thank you again Trent, and your whole staff, for the truly quality service and care for customer satisfaction!

    Kingly Review

    The euph is really quite excellent. The tone and ease of playing is exception for a horn in this price range. Intonation is pretty good too. I'm enjoying it. As always, ACB rules. K
