Product Overview

Introducing Coppernicus, the Double Shepherd's Crook Trumpet from Austin Custom Brass!

The ACB by Adams Coppernicus is an exceptionally versatile trumpet due to its great efficiency and broad tonal spectrum. There is so much room to explore and find your own sound on this instrument. No wonder it's so popular with our customers! Check out all of the videos on this page to hear a small sample of the possibilities:

Coppernicus is completely handmade by my friends at Adams in the Netherlands. After many years of collaborating on trumpet designs we decided to take our relationship to another level with the Coppernicus. This horn is an evolution from our previous instrument, the Hornet, and it's much more versatile both in sound shape and efficiency.

We intentionally designed this trumpet to be very mouthpiece sensitive. This is one of the things that makes Coppernicus so wonderful for road gigs or small clubs (or in this case the home studio). Enter a new sonic world just by switching up your mouthpiece! Check out how the sound changes over the 6 mouthpieces in this video:

But don't just take our word for how great this trumpet is, check out some of the reviews we've gotten from our customers who love it too!

Here is a review from our customer Richard Harris (3/27/19):

"The Coppernicus arrived today and it is BEAUTIFUL!!! I had previously owned an [Adams] A4, and although the horns look similar, there is no comparison in the way they play and respond. The Coppernicus is better in every way that the A4... the sound in every register of the instrument is better, and with the double shepherd's crooks, the horn can really take on a gorgeous, rich, robust tone that I believe to be superior in every way to the A4, which was itself a very good horn. Please pass on a string of superlatives to Trent and to Miel Adams for having designed and built ONE HELL OF A FINE HORN!!! I am going to flat out LOVE this fine instrument!" 


Hear how the Coppernicus compares with some other high-end instruments:


Here are some basic specs on the horn:

  • Copper plated finish
  • Poly bore setup to maximize efficiency and volume palette (overall feel is similar to a medium large horn)
  • 5.5 inch bell with extra large flare
  • Amado water keys
  • Double Shepherd's crook design
  • All-new valve block design
  • New leadpipe design
  • Recessed caps
  • Lightweight (lighter than a stock Bach Trumpet) and extremely well balanced in the hand
  • Completely handmade at the Adams factory (including valve block and copper plating)
  • Comes with the great Adams Gard single bag!
  • Mouthpiece not included (click here to see our Standard Series mouthpieces!)

Here's a review from our customer Steve on 1/2/19:

"The Coppernicus caught my eye because I love the look of copper. Knowing it was offered by ACB and made by Adams was the clincher. ACB has been my go-to for anything trumpet for a few years now and will be forever. I played the Coppernicus as soon as it arrived (which was very quick even though it was a week before Christmas) and totally love it!!! I’ve been playing for 57 years and other than the picc I got from ACB, the Coppernicus is my first non hand-me-down horn. Great horn from great people!!!" 


Due to the collaborative development process and proprietary construction, Coppernicus is available exclusively from ACB. We try to keep a couple in stock at all times to keep wait time to a minimum after you order. Email us at for more details and delivery schedules!

    Wow!!! This is my favorite. Playing it for five days, including 1 rehehearsal and 2 concerts it excels in slotting, tone, sound and build quality, and effortless projection. The moment Miel and Trent handed me this trumpet, I knew I had to have it. Thankks Miel and Trent for making a trumpet designed especially for me, sorry Trent!!!!
