Since its introduction in 2013, the 4147IB Custom Reserve has been an industry leader thanks to its innovative design and exceptional playability. Now, nearly a decade later, we have taken the 4147IB to another level.
Introducing the new, 4147IB “Ian Bousfield” Custom Reserve Tenor.
The list of improvements and enhancements to the 4147IB include:
- A New Single Radius, Rose Brass Sheet Tuning Slide Bow
- An Interchangeable, Yellow Brass Leadpipe (exclusive to the 4147IB)
- A Specially Weighted & Tempered, Dome Bronze Rotor Insert
- Newly Developed, Enhanced Handslide Construction Techniques
- New Custom Reserve “Elk Head” Bell Engraving
These design improvements are in addition to the 4147IB’s already impressive features.
Harmonic Pillar System
The 4147IB features a singular version of the patented Harmonic Pillar System based on a design originally developed for the Edwards T396-AR trombone. The 4147IB comes standard with two different Harmonic Pillars. One pillar is “soft” (copper) and one is “hard” (nickel). You can fine tune the trombone to your desired playing characteristics by choosing the pillar (soft or hard), the direction of threading (front or back), the depth of threading, or no pillar at all. Regardless of which setup is selected, players will notice a dramatic influence on the overall feel, response, and resonance of the trombone.
Handslide Cross Brass
From the beginning, the 4147IB featured a new concept and approach to the outer handslide cross brace. The entire brace design was examined with slide performance and player comfort in mind. Every aspect of the brace from the material, dimensions, weight, and location was fine tuned to match the overall 4147IB design perfectly. Perhaps the first thing you will notice is the more comfortable feel of the larger diameter brace. While playing, discerning trombonists will realize that the weight, alloy, and location combine to add balance to the handslide. Improving everything from slide action/responsiveness to the intimate feel of the trombone.
Noninvasive, Performance Bracing
Just like the original 4047DS and new 4047ET, the 4147IB utilizes several sophisticated bracing concepts within the bell section. Most noticeable is the Getzen “DS” double edge brace system. This system eliminates the tension inherent within most traditional bracing setups. In addition to the “DS” bracing, the 4147IB features the Asymmetrical Bracing first developed for the 4047DS. Asymmetrical Bracing incorporates both nickel silver and yellow brass alloys to create a more resonant, less restrictive bracing. Together, the bracing systems of the 4147IB combine to free both the F attachment and bell from the diminished resonance and responsiveness typical of most traditional, invasive trombone bracing systems.
Custom Reserve tenor trombones come standard in a Getzen exclusive fiberglass, vegan leather case. The case features adjustable interior padding, removable shoulder, and backpack straps, and a zippered exterior pocket sized for tablet storage. The case is highlighted by the premium, vegan leather exterior wrap. The high-grade material gives the luxurious look and feel of genuine distressed leather with the added benefit of abrasion, water, dirt, oil, and ultraviolet resistance. The fiberglass construction of this case provides much more protection than a typical gig bag while being much smaller and lighter than a traditional wood shell case.
