This could have been a GREAT product that I was sure to buy. However, not having a 9V power connection makes it completely useless to me and probably the vast majority of guitarists (who would like to put it on a pedal board).
Line 6: if you want to make sure sales will not be a total disaster, please include a 9V => USB convertor in the package (or add a 9V connection if still possible).
If not, you now know why this product will not sell well :)
