The Mapex Brass Master Snare Drum is one that comes in a variety of different sizes and isn't part of any larger drum kit that I'm aware of. I've used this snare drum in the studio where I was the engineer and not the player, as a session drummer brought the drum in with a few others to record with. He had some good drums in there but this is the one we went with for the song we were recording. It was a pop/country kind of song and this snare just seemed to work best for the tune. The snare has a great crack to it that cut through extremely well. The full kit was one from Slingerland and it blended in nicely. The Brass Masters snares do come in a variety of different sizes, although I'm not sure what the range is. The one that I've worked with was a 13" x 5.5" and I've seen other smaller sized ones, some as small as 3" deep. The one I used had a great sound with a lot of crack to it, and I can imagine that the smaller the depth, the tighter the sound. I think I even saw a piccolo version of this snare. I don't know all the materials at play are here but of course it's a brass snare and is quite heavy. The price is reasonable for a snare of this caliber, and I'm not sure if this changes for different sizes of the drum. It's definitely a professional's snare that isn't cheap or for those just starting out - if you're looking for something to swap out with your kit's snare drum for a different sound, this can definitely compliment your kit and add to your overall sound palette. The Mapex Brass Master Snare is worth checking out in any size if you're after a great snare drum to add to your collection.
