guitars

Personally, getting a setup where you are able to dial in a song and listen to it while hearing yourself play is the most critical long term skill.

Sorry it is not what you asked for here. Speaking from experience, I went down this path over 25 years ago and have little to show from the efforts. It is likely you'll be far better than me. Twenty five years ago, as a preteen with limited means, in a much smaller digital world, I never had this setup for listening and looping a recording. I learned tabs and chords. I had an old poster with a bunch of chords and scales. In terms of theory, relatively little stuck long term. I still gravitate towards playing those first dozen or so songs and rifts I learned even today. Looking back, the audio looping setup would have made me a much better guitarist if I had simply stuck to playing the songs perfectly and built my skills from there. Theory is like trying to grow a giant from a seed. Songs are like standing on the shoulders of giants.
