The Stradivarius Ultra and Elite are designed to enrich tone with clarity throughout the entire range. A patented tone intensifier on the Elite enhances the travel of air by directing the sound around and out with greater velocity. The patented tone intensifier also develops more vibrations to deliver more resonance. The stainless steel bottom creates a lightweight mute that is impervious to casual damage.
The Bach Stradivarius Elite mutes are made from aluminum with a rugged stainless steel bottom, and feature a patented "tone intensifier" for a clearer, more focused tone
