Before it became the Supraphonic in 1963, Ludwig's flagship snare drum was known as the Ludwig Super, and it was made with a chrome-over-brass shell. Of course, Ludwig have now reissued the Super snares, which come with nickel-plated hardware, but they do still offer the classic COB Supraphonic with chrome hardware, and this is one of them!

And what a drum it is!
 
This drum is super fat and crisp like a good brass snare should be. All the way from low-tuned Bun E Carlos tones to super-high-tuned jazz/hip-hop tones. Like an LM400 on steroids. Check out video demo!  
This is a B-Stock drum, meaning that there is a flaw in the plating somewhere. In the case of this drum, that flaw is on the inside of the shell, and you'd never have known had I not just told you, since the outside of this shell is flawless. The end result is that you get a phenomenal snare for less money! Ludwig's B-stock snares come with blue/olive badges and no serial numbers, hence the chopped badge.
 
Note the BR stamp behind the throwoff - that means that this drum is indeed a brass shell.
