I thought this would be gimmicky, but it's totes cool*. You can beam a Toneprint from your phone, *through your guitar pickups*, to the pedal. Check out the video:

A friend of mine who just got a Flashback delay just turned me on to this.
* That's Xbox One lingo, FYI.
Yeah, it's pretty awesome for checking out new sounds quickly and easily.
TC also launched a "build-your-own Toneprint" application that still uses USB, but promises to be totes versatile.
