We're giving one away in our current gear giveaway.
One of my editors has a unit for the in-depth review. It's a great concept. The rechargeable power supply sits on your board and can power it for anywhere from hours to days depending on the load. But in a live gig, no more ground loop issues! You don't have to worry that your pedalboard is plugged into a different circuit from your amp, etc... I am looking forward to knowing just how good/bad it is very soon...
In the meantime, the link in my signature will let you sign up to win one of these, or other cool gear.
