In a year since I've had it, the top of my Adamas SMT has sunk about 3/64 of an inch at the bridge.

How do I know this? Well... with all the shims out and the relief on the neck set to about .015, the elevation was right on the "book miniumum" of 2/32s and 2.5/32s.

The action was low. I thought it was my saddle getting grooves (its a little grooved, not much though...light actually). Now I see, I'm back to both shims and my action is just barely up to 2/32's and 2.5/32s (Like I could replace the thin shim with another thick one and be just about perfect). Same neck relief.

My only conclusion is that the top is sinking a bit. The neck certainly cant be moving against string pull... can it?

Bowl bend or top sinkage? Have you double checked the braces for disconnect as well?

Hmmm. I guess I better. This thing has literally never left my living room since it got here. Dunno how problems can start but.. better to check.

I've had lift, not sinking on my guitars. Some lift over time is normal. This sounds like you have to bring it to a pro for an evaluation. Keep us posted.

Took a look inside - no loose or seperated or broken braces. I see that the brace marks visible on the top of the guitar are "perhaps" a little more accentuated, but you still need to have a reflection on the top to see em. There is still visably some arch to the top.

This is strange. I'm not really an "acoustic" maven, solid bodies act so differently.
