I agree with Gilly - it’s always a good idea to do some reading/video-watching before tackling a job for the first time. ‘Bryan Kimsey Lutherie’ website and YT videos are also a good source of info.

Because I’ve been tweaking my guitars’ setups for over 60 years, I tend to forget that not everyone is comfortable with this kind of work, but I do firmly believe that most setup tasks are easily-learned by anyone with a modicum of nouse. It’s not rocket-surgery after all… ;-)
