Penzel Mueller Artist Enhanced Boehm Bb Clarinet

I am a retired musician/band director and am downsizing my personal collection.This is a Bb clarinet made by Penzel Mueller of Long Island, N. Y.It is an enhanced Boehm system. However, it is not a FULLY enhanced Boehm system. There is not the additional low Eb key.It does have: Forked LH Bb/Eb Articulated G#/C#’. Trill with right index finger. Keep G# key down. Trill from F# to G# Third ring for left hand (finger forked Eb clarion, and Bb altissimo). Using first and third fingers of the left hand. Simply lift middle finger. Extra third key for left hand. Play B,C, or C# (low E, F, F#) starting on left or right when next note is high Eb/D# or Ab/G#It is in need of a little tweeking to play well again hence the price.Not recommended for a beginner as it is vintage early 1900’s.Mouthpiece not included.The pads were invented by my first clarinet instructor.Please view my profile Thank youBoxed superb for everyday use. premium materials and excellent craftsmanship ensure long-lasting durability.
