Whew! What a multi-fx pedal this is.

This site will describe the Adrenalin III better than I can. When I got mine I've spent hours exploring this device and that's just foolin' with the presets.
"Beat synced effects" is what got my attention. I've used my Digitech RP300 and my Korg Electribe (groove machine) for my guitar playing. Now the Adrenalin III replaced them all and much better at it.
It's on my desert island list.
