You may well enjoy Tyler Woodford’s channel. He’s a Canadian luthier who could obviously create perfect artisan instruments from scratch but for some reason works as a guitar repair guy, the type who gets most of his work as referrals from other guitar techs who’ve refused the job because it’s beyond them.
A lot of the appeal is how unlike the stereotypical YouTuber he is- you never get a snazzy “before and after” reveal, in fact sometimes he barely gives you an “after” at all.
