Collection: Bach Trombone/Baritone/Euphonium Mouthpieces

About Shank Size/Selection

The shank is the part of the mouthpiece that fits into the instrument. Choosing the correct shank size is important because a mouthpiece must match the receiver of your instrument to fit and play properly.

A mouthpiece made for trombone, euphonium, or baritone will physically fit any instrument that uses that same shank size.

The Remington shank or stem is similar to the standard large shank trombone mouthpiece. The difference is the rate of taper. A modern large shank mouthpieces has a Morse taper .050" rise per inch length and the Remington style shanks have a taper similar to the Brown and Sharp taper .04167" rise per inch length.

Remington shanks were used in many vintage Conn large bore trombones starting in Elkhart, (1954-70) to Abilene, TX (1970-86) to Eastlake, OH (1986-92) Conn 8H, 88H, 60H, 62H, 70H-73H from around 1954 until the early 90's. PLEASE NOTE the modern Generation II 8H and 88H trombones use the standard large shank Morse taper mouthpiece offered on our website, not a Remington shank.

Why does it matter?

A standard Morse taper mouthpiece will not seat properly in a Remington receiver, it leaves a gap around the end of the shank which has a bad acoustic effect, this may cause bad slotting and for some notes to not speak as well as they should. A good rule is if it wobbles it's probably the wrong shank.
