Extendabone is an easy and inexpensive solution that will allow everyone to play trombone.

  • ERGONOMIC shape fits any hand of any size. Larger hands will hold farther down and smaller ones farther up. This lets the handle automatically adapt its length uniquely to every player.
  • INTUITIVE design is easy to use and understand. The thumb groove shows which direction the handle should be put onto the slide and the shepherd’s hook is easy to put on and take off when you need it. For quicker switching, you can fold it back so Extendabone is there whenever you need it, and out of the way when you don't.
  • SUPPORTIVE of good habits. Extendabone was designed to both support good existing slide technique and develop good slide technique for new players. The patent pending shape fills the empty space created when the thumb and first two fingers come together, which is the hand position of a good slide grip.
  • FUN! The bright colors and Tyrannosaurus Rex mascot were designed with an irreverent and child-like spirit. No one can look at Rex without smiling. He is just as happy to be able to play the trombone as you will be when you get Extendabone. Product Description
