This extension has manual low B flat or low B settings, which enables the player to play the range of the instrument without having to physically remove or connect the extension itself. In the low B (open) setting the horn will play normally in its usual range without significant tonal or pitch sacrifices. Twist the rotary valve shut and you will play a low B flat when fingering low B. Designed and crafted in Forrests' workshop by John Goebel in collaboration with Raymond Dusté the extension is made of black ABS plastic. Fits F. Lorée, new Cabart 74, and Fox instruments only.


This particular extension has a metal lined tenon and a 25mm tenon opening.   In good preowned condition.
