We now offer two versions of the Bullet Brace in order to accommodate more trombone models. The "S" brace included with the BB2002 model provides adequate room to fit most other manufacturers' trombones. However, some modification of the "S" brace may be required in order to fit the Bullet to your instrument. The "S" brace is built long to accommodate any such modification. The Bullet Brace is a descendant from our Stegeman bar, which has been in existence for six years. These items came into being from the requests of many players that wanted left arm relief from the many hours they were spending holding their instruments. The Stegeman bar is an "L" shaped brace that is soldered onto the receiver of the valve section. This brace helps redistribute the weight of the horn to the bigger lower muscles of the left arm. By redistributing the weight the bar takes the tension off of the smaller upper muscles in the wrist region. Many people get an imprint in the fleshy part of their left hand from the weight of their horn. The Bullet Brace and Stegeman bar eliminate these pressures and relieve discomfort that can occur from holding the instrument over a long period of time.
