"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
"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
"I'm a huge fan of the XO euphonium. The tone, pitch, and ergonomics are fantastic and allow me to do what I need to do without having to fight the instrument. It's the best pro horn I've played."
- Lance LaDuke, XO Artist
