It's very expensive this thing, $6500 or so, and there's been a lot of blog talk about how naff it looks.
Might be a nice gimmick but isn't it just like having an eBow on each string? Actually I'm a bit surprised Moog have done this, they didn't design it - they were approached by the inventor, and just as they were starting to do really well they've invested a lot into what could turn out to be a big white elephant.
