From what I can tell by the link, it isn't available yet.
That's a crowd sourcing site, if enough people pay in advance they will have the budget to get them made overseas and ship them out.
I don't know anything for certain but I do know "bling" when I see it and when you show somebody playing a 5 string bass through a 30 watt amp with 2-2.5" speakers as if that would sound like much more than a wet fart splatting on the sidewalk - then I become skeptical - very skeptical.
Where is the mic in the videos to capture that sound? A video camera? Or they are using it as an interface so it actually sounds good?
Sorry, I only have questions. Cheers, Kuru
