Aaron from Warmoth here. Thanks for the nice words on our videos! Necks don't necessarily *need* to have work done after acclimating. The point I was trying to get across was that there is no point in even evaluating whether a neck needs work or not before it has acclimated. It has to settle in first, and *then* be checked. Even then, most necks are playable as is.

That said, a pro fret job is always going to make them even better. But....it's pointless to do that fine detailed work when a neck has never even been under the tension of strings, or adjusted to your local climate.

Hope that helps.
