The handcrafted mechanism provides many additional features. The wing joint has an extra high E key and a link between the A and whisper keys. The boot joint has been extended with a detachable Ab/Bbtrill key. The wing joint and the narrow side of the boot joint are lined with synthetic resin. The bottom and the wide side of the boot joint have been lined with Luracast epoxy resin to above the A-flat to avoid damage from humidity. The 5 finger holes and the G tone hole are lined with nickel silver. The S91 Schreiber bassoon is everything an instrumentalist could wish for.
