You will be surprised at how versatile they are. I played the 2015 strung with Sadowsky flats and the 2001 strung with DR Sunbeams last night. To a casual observer, they look identical, but they can sound completely different. The 2015 is set up with the pickups lowered a bit, and it can get a soft, open, round sound. Whatever that means. The 2001 is far more aggressive and is quite a bit louder, with the pickups right up under the strings. It's pure aggression. Both played through an Acoustic USA 360M, which has endless clean headroom. No overbaked Ampeg sound for this boy. Set up one way, a Bird can thump with the best of them. Set up another way, a Bird can melt faces.
You probably should think about ergonomics more than sound, since a Bird can be set up to sound all different kinds of ways. It won't hang like a 7ender. Close, if you really want it to, but mostly, it's going to be a bit more neutral, allow you to move it around a bit more, and it's going to be easier to play if you set it a bit lower and swung around onto your hip instead of directly in front of you.
So, now you know everything you need to know to fearlessly buy one sight unseen. If it doesn't work, blame me. I'll be ducking under the nearest big flat rock.
