This horn is consistently warm sounding and easy to play on both sides of the instrument, making it the best new double horn option out there.
- Jennifer Kummer, XO Artist
"The XO 1634 is a groundbreaking instrument, combining that classic sound with a lightweight feel and a quick, free-blowing response, facilitating an ease of playing like no other horn of its kind."
- John Fedchock, XO Artist & 1634 Developer
"XO Trumpets are designed to deliver a gorgeous sound with an even register. This evenness allows me to play very efficiently, keeping clarity of tone and brilliance all the way through the most demanding performances."
- Steve O'Connor, Presidio Brass
