Have any of you guys tried one of these before? It's basically a digital mutli-effects board that does beat synched filtering, amp modelling, delay, modulation, and drum machines. It even has the option of an add on computer software that lets you edit sounds or use the internal filters to create sounds from the ground up on your PC and then transfer them back to the pedal.

It's got a pretty hefty price tag on it, but it seems like it will make some really great sounds. A lot of artists are using it these days, Greenday used it for the beat synched tremelo on Boulevard of Broken Dreams, and John Mayer uses it all the time, he even has a giant midi-board setup when he plays live to give him quick access to a number of it's presets.

Heres Mayer using it for a weird envelope auto-wah sound:

Here the random flanger setting is making that crazy accordian like motif at the beginning and throughout the song:

Here's someone demoing the presets:
