I don’t have any clue about guitars and i am buying a Jackson JS20 dinky. Can i be good at it just by getting free online lessons? How is the guitar as a beginners guitar?
Can you learn how to play guitar on your own, just from the internet?
Yes. Doesn’t mean you’ll do it right, though. As the other answer suggested, learning on your own means you *will* have bad habits and incorrect technique. I know, because that’s how it happened with me…. I never had enough money to afford a teacher, so I just taught myself. Worked out pretty well, for the most part, but it wasn’t until years had passed that I began to realize that there were problems with my technique, problems that if I would’ve had a teacher that would have never shown up.
As a result, I did have to "unlearn" how to play and figure out how to do it correctly. My speed, coordination, and enjoyment did increase once I began ironing out my issues, but if I would’ve had good instruction from the start I would be a lot better by now.
My suggestion is to either get a teacher to learn the basics (how to hold your hand, how to fret a note, how to play a chord cleanly, how to run scales) at the very least, or if you are in the same place that I was when I started out, at least find the best guitar player you can jam with and study them like a hawk, ask them questions, etc.
You should have no issues with that guitar, its perfectly fine for a beginner. I *strongly* urge you to get it properly setup and intonated, though! This is something I never really understood for years, but a proper setup and intonation means that your guitar will play better, will stay in tune better, and will sound in tune with itself when you play higher up the fretboard.
Research your butt off – no teacher means you need to absorb a lot of information to make up for it! Youtube is an excellent resource that I didn’t have when I was starting out – so spend hours studying how they do it, it should help you out greatly!
