Re: Removing temolo shims
What you mention is what I'm concerned about. I expect that my action isn't going to be consistent and I may get some fret buzz on the higher frets, depending on how I try to compensate by adjusting the action. But I also have a Les Paul with a similar fretboard radius and a flat bridge, and don't have issues with it. What I may do is keep the one shim under the D and G, and remove the others.
If this was the only guitar I played, I'd just try to get use to the curvature of the bridge, but switching between guitars throws me off.
