I opened the UPS box and have been playing it for the last couple hours. It's a great guitar. Actually, more balanced than I expected. It doesn't boom like I expected - but does have a very pronounced low end. I had heard that the D28's where great on the bass - but lacked in the mid/high area. I don't see it with this guitar. It's strung up with Elixer's. I'll be curious how a set of Martin strings sounds on it.
I look forward to seeing how it sounds in 25 years. I'm not a rich guy and am pretty sure this is it for me with guitars. Unlike some that buy and baby - I'll be playing the heck out of this thing. I'm sure it will open up nicely. Everything I've read about the standard X bracing indicates it will only improve - even better than the scalloped bracing of, say, the HD-28.
There are some things that I believe everyone deserves and should seek out:
1) A spouse who loves, understands & appreciates you
2) A great pet
3) Fine quality instruments
You can get average versions of all of these - but you get what you pay for.
