I’m not sure if you’re referring to favorite or best sounding snare I’ve ever heard, or of the ones I own.
As far as the latter, well, I have two, both from PDP: 5.5x14” FS birch, natural to charcoal finish, and 5x13” metal snare. The metal snare I’ll never part with it, since it was a gift from the Mrs. The FS, I’m not attached to it, but it sounds ok.
As far as my favorite snare, I’ll have to say it’s John Bonham’s Ludwig Supraphonic 402, 6.5x14”. I wrote an article a while back about my five favorite snare drum sounds:
Great Snares of Rock
I was able to get a response from a couple of the players of these great snares; they are quoted in the article about the specifics of their snare. And Andy! If you or any readers of the article can help me with the specifics of the #4 snare, that would be great. I’m still not sure (all I know is that it sounds awesome!).
The next time I’m in the market, I’m going for the Bonham snare!
