I've had mine for almost 2 weeks now. I am not primarily a guitarist, so my playing ability and 'tone pickiness' are not very refined, but it's great for me. Lots of versatility and light years ahead of what I was using before. Definitely worth (to me anyway) the extra money for the Pro, if only to throw it in the rack.
My primary guitar playing is only to add some parts to original tunes I've written - so far I've had no issues trying to dial in a sound that I've got in my head.
