Originally developed for the Edwards T396-A trombone, the patented Harmonic Pillar system allowed musicians to acoustically tune their instrument for the first time. A singular version of that revolutionary tool is now available from Getzen on the all new 4147IB Custom Reserve. The 4147IB comes standard with two different pillars; a hard and a soft alloy. In essence, giving trombonists the power to choose between three different trombone setups. The hard pillar, the soft pillar, or no pillar at all. Regardless of which is selected, players will immediately notice a dramatic effect on the feel, response, and resonance of the trombone, allowing them to dial in the 4147IB to meet their performance needs.

Among the long list of Getzen firsts on the 4147IB is an all new concept and approach to the outer hand slide cross brace. The entire brace design was examined with performance and comfort in mind. Every aspect of the brace from the material, dimensions, weight, and location were fine tuned to match the 4147IB perfectly. Perhaps the first thing a player 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 hand slide. Improving everything from slide action and responsiveness to the overall,intimate feel of the new trombone.

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 traditional bracing. In addition to the "DS" bracing, the 4147IB also features an Asymmetrical Bracing system first developed for the 4047DS. Asymmetrical Bracing incorporates both nickel silver and yellow brass alloys to create a less invasive bracing setup. Together, the bracing systems combine to free both the F attachment and bell from the diminished resonance and responsiveness typical of modern day trombone bracing designs.

The 4147IB Custom Reserve is available in a Getzen exclusive fiberglass shell case. The case features adjustable interior padding and backpack straps. It is one of the smallest large bore, tenor trombone cases on the market today providing more protection than a traditional gig bag while remaining lightweight.
