Find a comfortable guitar. The mechanics of it can be upgraded at will. My second favorite guitar to play is a cheap starter pack guitar I'm learning tech work on. Bought it for like 80 dollars at a guitar center a few years ago and it was just comfortable. You don't have to spend a lot. Ended up liking it good enough after getting it set up correctly. The tuners got switched first.

I recommend avoiding amps with modeling or anything overly complicated, unless you're really into that. They can be great and my wife uses one for her bass and it's great. The reason I avoid them and recommend others to, is simply just because prior to this we would use pedals and other toys to kind of get us past those plateaus and learn the sounds and stuff. If you buy it all at once you may lose a little if that. Once you get the hang of a few pedals and the various tonal adjustments, then look at modeling.

All you need is a few chords and tone options and you can start playing around learning it all. Don't worry about tube or solid state, go for the sound and style you want.

Like anyone else will say, Justin guitars is a good as it gets. It's great and the free stuff is all you need. It's as good as paid online stuff I've signed up for. There is also syngates, but I'd learn the basics and start with Justin guitars. Use the other way down the road for what you miss or need another perspective on. It is good though.

If you start with acoustic, I'd spend a little more on a better quality instrument, maybe 200 to 300 and a hard case. A cheap case is fine, just needs decent hinges.

And Justin guitars. I really wish I could have started with it and it's still been great. Don't worry about theory yet. Learn a few chords and sounds first. A cheap keyboard and children piano theory book prior to learning guitar theory can help understand it. I learned guitar as an adult, but used my kids keyboard to start their because I struggled and quit trying the first couple times.

Explore lots of music and don't be scared of the wah
