After nearly two years of behind-the-scenes consultation, development, and testing, we are extremely excited to officially introduce the trombone world to the next generation of Custom Reserve tenor trombones

Built on the foundation laid by the original 4047DS, the 4047 showcases an impressive list of new design features that include:

• • A New Single Radius, Yellow Brass Sheet Tuning Slide Bow
  • Our Patented, Harmonic Pillar System (includes one hard and one soft pillar)
  • An Interchangeable, Sterling Silver Leadpipe (exclusive to the 4047)
  • A Specially Weighted & Tempered, Dome Bronze Rotor Insert
  • Newly Developed, Enhanced Handslide Construction Techniques

• New Custom Reserve “Elk Head” Bell Engraving

In addition, the 4047 Custom Reserve shares many of the same design elements that made the original 4047DS trombone so popular.

• Asymmetrical bracing that incorporates the use of both nickel silver and yellow brass, creating a balance within the bracing that adds to the harmonic resonance.
• Enhanced, Getzen PowerBore rotors combine the tried and true benefits of a conventional rotor with proprietary improvements including specially machined passageways and variegated rotor caps.
• “DS” Dual Edge Bracing derived from the famous Edwards Instruments Edge Bracing design. This innovative bracing frees the bell section from inherent stresses caused by traditional, more invasive bracing systems. Improving both response and overall resonance/liveliness of the trombone.
• A wide-style handslide with solid nickel silver cork barrels for added strength and mass in the inner handslide assembly.
