Reddit mentions of Mel Bay Six Essential Fingerings for the Jazz Guitarist (The Jimmy Bruno Jazz Guitar Series)

Well if you did DJing then your creative streak is buried shallow in you so you may have some success learning guitar by experimenting. Few years back I was hosting a "couch surfer" from New York. She was a singer songwriter playing a gig in Austin. I played guitar for at least 20 yrs longer than she did but I still learned from her. She had this relentless drive to experiment and make new things on guitar. Most of it she probably did not understand from theoretical point of view but it sounded interesting.
I come from classical guitar as my first instrument so I always played a lot from written score. And that spirit of experimentation was a nice reminder.

Also biography of every rock musician usually starts with "when he was 12 his uncle gave him guitar and little Jimmy spent next two years playing melodies he heard on radio". That is VERY important - ear training - good ears will make your music career much much faster.

Anyways. You need some technical framework - correct way of sitting, holding guitar , fretting, picking, correct fingerlings for playing scales etc. for that I would recommend taking few lessons. Basic technique can make or break you. I have a friend who spend first few years playing guitar in a recliner chair and now has to struggle because of the habits he learned. You can get away with online sources like eg. courses at www.truefire.com or Julian Sander website. Make sure you get a mirror (no kidding) and practice in front of - that will allow you to correct a lot of errors. For scale playing I would suggest Jimmy Bruno book - it will give you left hand basic patterns that are ergonomically sound:

One more thing. Beginners often learn few big 6 string chords and then think that somehow every chord must be like that - utilize all 6 strings. That often slow people down. It is essential that you understand and can play chords as on 3 or 4 strings and understand basic structure - can name notes in the chord root (if present), 3rd, 5th (if present), 6th or 7th, 9th. That knowledge and ability to play such smaller 3-4 note forms of the chord all over the neck will allow you to improvise you based on chords and not on "boxes".

Almost forgot. As soon as you start making stuff up on guitar - get a simple looper eg TC Electronics Ditto. And start layering things. Making up little riffs and mini songs. That will do wonders to your musicianship.

Good luck.
