You need a set up by a competent Luthier.
I own a 2003 and a 2010 standard Bird. Not all Birds are equal. I had to play several from GC, Sam Ash, Best Buy, small guitar stores until I found these two.
In my search the biggest downer was the low E string giving a "Thud" sound, At least 4 of the Birds I played had the "Thud" problem. (J45s too)
Now that being said, I am sure if the stores spent the time to change strings, adjust the neck, check out the saddle and nut, and frets, those Birds would probably play fine.
The 2003 has had two setups, the 2010 has needed no set ups, really didn't need strings but i changed them anyway.
There is something about that HummingBird tone that enthralls me. My favorite acoustic guitar for sure.
