I usually change strings about once a month. When I do that, I just change 1 string at a time. But, about once a year or so, I like to do a major P.M.
(preventative maintenance) and remove all strings, polish frets,clean and condition fretboard, clean and polish hardware and body of guitar. After restringing, then I will go through the entire setup which I have become comfortable with after watching many instructional (YouTube, etc.) videos.
The secret is to only make very minor adjustments when tweaking the truss rod. If you are not comfortable with that, you could do all of the other tasks and then let a local luthier do the final intonation adjustments...but it's really not that difficult. I think my method will prolong the life of the guitar and improve playability in the long run.
Judge a band by the guitars they keep. If there are no Telecasters in play,move on.
