straight forward question which one of these books would you recommend for an advanced tuner that is starting out meaning someone that have already studied tuning on the internet from watching videos(goat rope garage youtube channel particulary as foundation videos and alot other) , reading articles,posts ,asking questions....etc for no less than a year until reaching a point where there is nothing more to learn so basically which one of these tuning books would you recommend to someone like this who wants to make sure he learned everything .
since there is alot of books and courses out there but no one really have a clear review about them .
