Product Overview

Adams A4 Bb Trumpet - Amazingly Rich Sound!

The A4 is one of the most popular models in the Adams trumpet line. 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. The larger bell diameter, bell flare shape, and lighter gauge bell give you exceptional feedback behind the horn and good sound dispersion out front. This is one of the heavier models of Adams trumpets, but is incredibly versatile: it will work in many different musical environments due to wonderful coloring and richness of the sound.

The A4 is a result of extensive collaborative design work with Adams Performing Artist Amik Guerra, who says:

"You know, as a professional musician you always want to have an instrument which is just, expressing what you have in your head. In some ways it's like an amplifier of what you have inside. And you've got to have the best amplifier.

"The relationship between a musician and an instrument is really close. As I came to Adams with the idea of the A4 I had really specific needs and ideas about how I wanted the horn to sound, the flexibility, the playability the intonation... It's also what I needed for my shows. I hear the sound in my head, but I needed a hand which will put this together.

"And of course as a musician and not as an instrument builder, you have all these ideas that sometimes are not even compatible, and you need someone who is going to make them work together. We had a really long year of work with Miel Adams to find the way, and these needs I really wanted, and all these ideas which I wanted to put together. And at the end of one year of work, i was like:

"Oh, this is the instrument I was dreaming of for my whole life! And it covered everything I really wanted and needed in my horn."

    Adams A4

    Visually a beautiful instrument. More important it plays quite easily. Stays in tune throughout the entire range. Just feels right. I'm enjoying the horn more than I thought possible. A wonderful change after 60 years of one manufacturer's instruments.

    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!!

    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++
