I made this a few weeks ago using all Amarillo, and it's all kegged and ready to go. I compared it to the real Gumball Head
The one on the right is the home brew. The photo sucks, but basically the colors were very similar with the real GBH being way clearer. The home brew was slightly darker.
As for flavor, they were both EXTREMELY similar. I think mine was a bit more bitter and had a lot more of the Amarillo flavor and aroma, but I'm guessing it has a lot to do with how fresh it was compared to the real GBH. I also think the real GBH has a candy-like sweet flavor that makes it addicting as hell, and my brew was lacking that. Overall, though, they were very close.
I had to change the AG recipe around because of my normal efficiency. Here it is:

I think my thermometer is off - it ended up finishing at 1.007! The OG was 1.051, so this beer is 5.9%. Even with all the extra alcohol, I was pleased with how close it was to the real thing.
It's disappearing fast!
