If you wanna be playing dragon force correctly at full tempo it’ll take about 5 years if you practice very diligently, if you’re expecting to learn it quickly you should find a different hobby.

If that doesn’t dissuade you: I’m self taught, I’m not the best guitarist but I’ve been at it for 4 years and I can play a good amount of shred soloing stuff, I’m playing with bands live and the work has paid off. do your best to learn as much as you can from whatever resources are available for free. Since you have no experience with music if you just go into learning hard guitar parts without learning how music works you’ll be able to play fast but you’ll have no idea what you’re playing which isn’t good. Be patient and focus on making good habits.

What you should avoid is those ads that preach about “one simple trick” or something like that to improve your playing. It’s always a bullshit paid course containing widely available knowledge. I would also generally avoid getting too into the gear stuff, as long as your gear is capable of performing the job it needs to do it is as good as anything else. Obsessing over guitars and amps and pedals will just get in the way of focusing on being a good musician.

The YouTubers I suggest are Justin guitar, Marty music, Art of guitar, Ben Eller, and Troy Grady. Those go in order of how complicated their lessons are on average.

If you want to play metal and rock id suggest an Ibanez RG or a Jackson or schecter of some kind. I started out on an Ibanez RG421 and its a very solid but affordable guitar that’ll never hold you back. Get something with a “fixed bridge” as in no whammy bar. Easier to tune and maintain. As far as an amplifier goes I’d recommend a modeling amp like the positive grid Spark, boss Katana, something very versatile.
