We just got one in my GC and man I might pick one of these up for a back up head! It's sooo tiny and light but puts out that signature GK sound at a whopping 500W. Priced at a price 599$, that's not bad. (Unbelievable price for employees hehe ) I didn't get to play with it too much with the G.I.V.E Technology off but my first right off the bat impression was it was pretty clean with no grit. But the G.I.V.E Technology is so rad.
