Since the introduction of the original 4047DS trombone in 2011 and the 4147IB “Ian Bousfield” model in 2013, the Custom Reserve line of tenor trombones has become a top choice for elite trombonists around the world. Their innovative designs, attention to detail, and performance-first approach have taken the Custom Reserve trombones to the next level, marking the difference between true artistic expression and just being a trombone player. With standard premium features like “DS” edge bracing, PowerBore conventional rotors, and variegated rotor caps, the Custom Reserve line rivals anything offered by even the finest “boutique” shops.
