The mute itself does. The "cage" that surrounds and covers the mute does not. It's an integral part of the casting. When Ric folks talk about "teeth" on the bridge, that cagelike thing is what they're referring to.

A lot of people here don't get that Rick has its niche, seems satisfied with it, and doesn't want to become FMIC. They have people willing to pay exorbitant prices for EVERY INSTRUMENT THEY MAKE, both new and used.
