I got my first guitar in about 95 and have been totally self taught. I stagnated massively for around 15 years in the middle when I infrequently played then got frustrated all I could do was some Nirvana power chords.
Started playing again around 5 years ago and had my guitar professionally setup - what a world of difference that made! I’ve made decent progress since but it’s still all just the odd riff or solo here and there and there’s a lot I can do a lot better. Using YouTube videos is only getting me so far and some 1 on 1 I hope will do the trick.
My wife started taking piano lessons and it inspired me to do the same for guitar. I’m sure it will be helpful even if they’re going to rip my technique up and start again.
Have you had lessons or are you self taught? What helped the most for your playing?
Recording. An audio interface can be found for dirt cheap, and you can learn the basics of a DAW in a day or so.
Then find a drum base online, and play on top of it. You make mistakes, you delete your take and do it again. Forces you to practice, to put on the table all the techniques you know, and also to think about the overall structure of a whole song.
