I just had my ASAT neck replaced under warranty. It originally had a birds eye fretboard, but most everyone involved in the process (from G&L to my luthier) felt the birds eye fretboard contributed to the failure of the neck. For the record it was also a 3 bolt, bi-cut neck as well.
Mine was an '05 & I bought it new, so they honored the warranty.
I do love this bass & I have to say that the birds eye was gorgeous & I was bummed about losing it.

If you have problems contact Chris Robeson (sp?) at G&L. He's in charge of warranty repairs there & is a top notch guy.
