Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It sits between your existing mouthpiece and the horn's leadpipe, so you keep playing on the mouthpiece you already use.
No. This version is built for French horn shanks. Buzzing devices are made in instrument-specific sizes and are not interchangeable.
No. It is a buzzing aid for warmups and embouchure work. It does not quiet the horn for normal playing.
Free buzzing has almost no resistance and you hold the mouthpiece in your hand. This adds back pressure and keeps you in full playing position.
