The A4 is one of the most popular models in the Adams trumpet line. This horn is a result of extensive collaborative design work with Adams Performing Artist Amik Guerra. This is one of the heavier models of Adams trumpets. Featuring a 5.5-inch one-piece bell and a heavy chassis, this horn is an ideal choice for the soloist looking for an extremely rich, warm, fluid, and thick sounding horn. One of the great things about this instrument is its versatility: it will work in many different musical environments due to wonderful coloring and richness of the sound.

Adams A4
Written by Mathew Willis on 26th Nov 2019

Thia horn is simply everything I have been looking for. Beautiful construction but more importantly, so easy to play. I immediately felt a difference when I started playing this horn. The tone palate, while warm, is very flexible. The upper register speaks beautifully, and the horn is simply a joy to play. Thank you ACB!!

Beautiful people, beautiful horn

I can’t stress enough how welcoming, informative, and perfect this experience was. I learned more about trumpets in a few hours working with these guys, and thanks to Trent for helping me find the best horn for me, for what I want. A++
