A guitar is a huge gigantic chick magnet sitting in your lap. If you play well it can be a great tool to draw women to you.
It's just a tool though or a gimick to aid you in pick up. It's not pick up. Don't rely on it. It's meant to be used as a supliment.
If your game sucks it won't help you. If your game is good it's just another tool of the trade like openers, except now you don't need an opener
. Just keep in mind that you have to play well (and it doesn't hurt to be able to sing half way decently as well). If you're good at playing guitar and it's something you genuinely love to do it could be a great tool for you.
I'll tell you from experience it works wonders outside on a college campus under a tree near a dormitory.
Tips
1. Play well known and current catchy upbeat pop songs (basically chick friendly music). If you sing as well as play and have a fun attitude people will flock to you. Women come with the crowd. It's game on from there. Just have fun with it. Make sure you're following general rules of pick up.
If you play your own music test it out on a female friend first. Most women aren't into death metal. It is possible to play R'n'B songs on an acoustic guitar. I was in a metal band in college, but when I played for women I'd play bluesy acoustic rock.
2. Get a band. Grab a couple of buddies and play outside. By that I mean a singer and 2 guitarists or a guitarist and a bass player, and someone can drum on trash cans or picknic tables. Now you have a show and a show will bring an audience. Make sure the guys are not as good at PUA as you. Teach them a little PUA so they aren't total AFCs but not too much. You want them just cool enough to not make you look bad, but not cool enough to compete with you.
Luckily most musicians and artists are natural AFCs
3. Play outside as often as you can in an area where lots of people are around. When it snows or rains play in a caffe or a pub that has an open mic night.
4. Put out a hat for money and say it's going to "charity". Charity is another gimick and a chick magnet.
Charity gets pussy... especially from "nice/good" girls.(Note: this can backfire if it doesn't actually go to charity or a cause. Don't lie. You'll get caught and you'll have to work hard later on to fix it if you can fix it)
5. Pretend you're a rock god and all the chicks already love you so just put yourself in that mindset and they will feel it.
7. Get the girls to sing along and join in so they are involved with the act having fun with you.
8. Just basically put on a good show. It's not about the music as much as it is about the act when you're playing to pick up chicks.
Hope this helps. Just keep in mind, if this is all you do you will not pick up chicks. You can't just pick up a guitar and expect to be fucking like a rock star just like that. You gotta have game too.
I used to do this in college all the time, but I was a total AFC back then and had no game whatsoever. Playing guitar was a crutch for me. I thought playing guitar was what attracted women to me, but really they weren't into me they were into my music and the show. Playing guitar works well for drawing women in and meeting lots of girls at one time, but it won't make them feel attraction unless you are already a player.
Read alot of pick up literature and stuff on this forum and use it when you put on a show. Once you have some game playing guitar can get you alot of pussy in addition to what you're already getting.
