Well, looking at the display on it I'm going to say that it isn't some boutique company or someone we've never heard of. This is one of the corporations. Because this is obviously pretty advanced, would require a fair bit of funding I think. I don't think it's a Peterson tuner 'cause they have a very distinctive look to the display that they would probably look to be keeping.
I reckon it could easily be Korg, and would put my money on them before anyone else. The red and green against black display thing just says "Korg" to me. But I guess we'll just have to wait and see...
