I don’t like posting my personal shyt online but I have a wide collection from Fenders to Gibsons. Let me start off by saying that it’s NEVER too late to learn and it’s a great hobby to mentally stimulate you.
I’ve been playing for over 20 years and I still learn something new everyday.
The first thing I’ll say is that it’s vital you get the best equipment from the amp to the guitar itself. If you’re playing on some crappy gear, you will lose motivation. So if you’re going acoustic, you can’t go wrong with an expensive Yamaha. Always go for a Marshall amp.
In terms of electric guitars, I prefer a fender telecaster because it gives me that Prince sound, with a bluesy kinda tone. A Les Paul Gibson can give you a similar sound too but it’s more crunchier.
If you want to move to electric, it’s best to go to a guitar shop and ask one of the employees to test each one out. Make sure you flash the cash so they know you’re serious. They don’t want some window shopper wasting their time with no intention to buy.
Once you’ve chosen the right equipment, start learning about scales and chords. I don’t know how much you understand musicology but scales will make learning and playing guitar (and any instrument for that matter) easier. You have to learn it otherwise looking at the fret board of the guitar will seem intimidating.
I had to learn reading books and watching others. You’re lucky that we have the internet so there are plenty of videos to help you. Once you understand scales and chords, you can play anything.
Remember, when playing scales, take your time, build up your speed slowly and never forgot to incorporate your pinky finger. Once you learn the basics, you’ll be doing things like slides, hammer ons/pull offs, palm muting, economy picking, pinch harmonics etc. It sounds foreign to you now but you’ll naturally incorporate these things as you learn.
Good luck and remember to have fun.
