Interesting. They look like they'd respond a lot like the lace Alumitones. I'm tempted to try some, but it seems like they might be kind of bland, especially since they're supposed to have a perfectly flat EQ.
They look sexy.

I agree they look amazing (aesthetically), but that clip they have on the site isn't inspiring me to spend $160 plus $22 shipping for a single pickup. I'd be more convinced if they had more samples or had given them out to some well known artist and had them mess with them a bit.

It seems like they can be highly tweaked, but idk...
