Learned about it on facebook today. Makes so much sense to me - and the pro feedback looks good! Sometimes it's the small things... that get overlooked. I'm sure other manufacturers will follow.
Seems like a fine concept, is it a totally new line of heads or does it apply to all?
I guess we'll see when they're released if there's much of a noticeable difference in sound, tuning range or feel.
I'm glad they're still pushing to make their products better though.
Honestly, I don't even understand the point of the collar. I tried a Remo snare side ambassador without the collar once, and as soon as it was on, it stretched - and thus, a perfectly fitting collar was born. I feel like a deeper collar might work really well for some drums, but be awful for anything with a edge different from the standard 45. I've never tried a thicker batter head without a collar, but I would love to. Perhaps it would be too thick to stretch, but it sounds like a plausible idea in my head.
And the head is just going to get stretched to that "perfect" shape when it's tightened onto the drum.
That depends on how imperfect the shape was, and how much you tighten it. Part of Evan's claim is that you get better sound at low tunings, where there'd be less stretch.
I wonder if the ability to tune lower will impact the life of the head at all, not stretching it as much seems like it would extend the life a bit, if you're not a hard hitter.
I find it tends to go the other way that the more tension the longer they last as the impact is spread out over the whole head more efficiently.
