After playing my D2H for a couple of weeks I started to notice buzzing on the 6th, 4th, and 2nd strings so I took it to my local shop where they adjusted the neck relief. The action was a bit higher, the sound lost some bite and the buzzing ceased EXCEPT for the B string. I guess I have a pretty aggresive flatpick attack but apparantly the 2nd string is notorious for buzzes. I tried another D2H and other guitars and I notice that same buzz, more or less. Do you have that buzz on your Collings? What do you do, if anything, about that?

No buzzing on either my D2H or my CJ and I play pretty hard with fairly heavy picks. The neck on each is just about flat, i.e., not much relief at all. What gauge strings do you have on it? If you've got lights try mediums and see if the buzz goes away. You might need a complete setup (new saddle and possibly new nut) with your string gauge of choice. Both of mine were setup at the factory for my fairly heavy handed playing. Low E at the 12th fret is around 7/64" on each, I believe (I'm at work right now so I can't check it).

I forgot to specify that the 2nd string buzzes when I fret a note (from the 1st fret on) with an aggresive attack. The set up guy said the adjusted relief is now very loose, so I don't know whether that means the neck is almost flat or not. The strings are mediums. I'm going to get my own ball-end hex wrench and attempt some tweaking to increase the playability. Anything I should know before the fun begins?

You should put a handle on the short end of your hex wrench. I fashioned one out of a length of wooden dowel. Also, a little adjustment goes a long way on these Collings necks. No more than 1/8 turn increments.

Another thing you might check is if the guitar is dry. If you've got a hump in the fret board at the body fret you might have a dry guitar and that might be where the string is buzzing.
