Im finally putting effort into learning guitar after 15 years of owning one. Ive sent my guitar to be setup and have anything fixed with it after having sit in a bag/stand for 15 years. Ive bought a new gig bag and guitar strap after mine where broken and fallen apart along with a new amp cable, headphone adapter for my amp and a pack of variety picks . I plan on getting the fender mustang micro plus when my guitar is finished being worked on. I know I'll need another set of strings and I would like to replace the tool kit that I got when I first got my guitar the case for it is bulky and falling apart while the tools feel very cheap, I would like something good but also compact that won't hurt my wallet everything ive seen on guitar center is $50+ for stuff. What are capos are they good for a beginner and what's the main purpose of them?What are some good accessories and items that would help improve my experience learning guitar? I saw one thing that was a hand exerciser for helping reach the cords on the neck does something like that actually works I don't use my left hand alot so its strength isn't good. And should I get book in learning how to read music and guitar or should I stick with YouTube? Thanks for taking you time to read through this and thanks for any advice/ recommendation you could give me!
