Guitar and Piano are two entirely different beasts. The guitar has a lot of timbral versatility to it compared to the piano. For example, the 6th fret on the low E string is the same pitch as the 1st fret on the A string, but they have relatively different sounds because resonance gets involved. It's quite a fun instrument to play however. If you're leaning to play Electric, get a Squier Strat. Every guitar player you know is probably gonna tell you otherwise, because, it sounds bad or isn't the greatest guitar in the world. While that is true, it's also cheap, and compared to One Act guitars, it's not too bad. It's less than $250 for the pack with the amp and the tuner, cable, bag, and everything else, and it's not a bad set. I'm still using the gig bag I got from it 5 years later on my Iceman. The amp eventually went because I used it outside in awfully humid conditions and the electrics corroded over. But for the short term, it's a good investment. When you first pick up an instrument to learn, you need to develop your practice skills, both mechanics and regularly practicing, so don't spend $400 on a guitar right away. It's a shame to see people spend $500+ on Epiphone Les Pauls and knock offs, learn how to play a few songs, and then give up and have the guitar stuffed in a closet. If you do get the set, there's usually a book included where it teaches you a few notes on each string, then some chords, gives you some basic songs, with notes and chords. Nothing to deep into the theory but use that in learning the mechanics, which'll eventually help you in the theory. Go through the book, make sure you know it, then go to a teacher, who will teach you (ideally) advanced mechanics, then start introducing theory. Some people say to learn how to play tabs which are very helpful if you want to learn a song or a new technique but stick with the standard notation because it'll honestly help you. Guitar isn't necessarily difficult to learn if you're willing to put in the time to practice, but it's ridiculously rewarding to play.
