I'm usually down on M:Audio for their boring, ugly boxes, but now they've come with a interesting (if slightly ugly) box. The Black Box (great name!) is a neat little guitar amp modeller/effects box/sound card.
The interesting thing is that it includes technology from Roger Linn's everybody-says-it's-brilliant Adrenalinn guitar effects box. $299.95 seems reasonable, considering the Adrenalinn itself is $499.
