Unless you really want a black drum, just buy a Supra.
Not to be a d*ck, but that's really shortsighted and very simplistic.
I assume others saw my post a few down there, so I won't go into the differences I hear being as I OWN both drums.
Yes, a Supra (and the Acro) is a great drum, but the sound of it might not work for someone---just as a BB might not be the sound someone else wants.
They asked about differences between the 2 drums, and not something like your first comment.
You're right, they should play both if possible to see which one might work better for them (if that's possible), but if it's NOT possible to play a drum, a real description is very helpful in making a better choice when you're spending a few hundred bucks.
Again, I'm not setting out to be a jerk, sorry if you think I'm "going after you".
I'm not, but comments like the first part are just no help.
I think it IS safe to say that if someone like's the sound of the Ludwig Brass shell, but
doesn't want a Black drum they should try (or buy) the Brass Edition snares.
Anything
could be
said to be a COB on an eBay description (especially if it's a little older, has a B/O badge or a older Keystone), but you'd have to BUY it and
then find out.
If someone was not real familiar, or not experienced in what years/models
were Brass shells, they could get screwed by a bad description, or seller with a misleading description like "same year as the brass shelled drums" or something like that.
So be as careful as you can and look things up and ask questions, just don't buy something---unless you have money to burn.
There's also a lot of difference in sound between the Acro and the Supra too, and SJR pointed them out pretty accurately.
