While there are a lot (I mean a looooot) of guitar channels on YouTube, so many of them are only of the vapid reactionary meme-y type. There are instructional channels, but many of them are very dry and not quite fitting to a video platform (they should be articles or chapters in a book instead). A good channel properly utilizes video shooting and editing, showing close-up details of each hand as it’s playing, while the instructor is engaging (a little bit of humor and wit goes a long way too). A recent discovery that more than handles these requirements is Ben Eller. Yes, some of his recent videos are reactions, but I suppose any large channel has no choice to maintain and continue growing. I will certainly skip them.
Of his many videos, my favorite I’ve found so far include Getting the most out of your new guitar, This Will Improve Your Picking, Fix Your Picking Hand, and Taking a Break from Guitar.
