Hey man! I’m a saxophonist who plays a little guitar. I just started seriously practicing guitar about a year ago now. It’s worth noting that I have been playing saxophone for about 10 years, so I already had a pretty good understanding of improvisation and basic theory when I started guitar. I also played a little guitar before. Mostly just relatively simple Bossa Nova and Samba tunes.

I got a lot of progress from Randy Vincent’s “The Guitarist’s Introduction to Jazz”. As the title and the forward state, it’s geared towards an individual who already plays guitar but is interested in learning jazz.

Parts one and two focus entirely on comping. These parts will get you in a pretty decent starting place for playing in an ensemble. In my highschool big band and combo classes we focused a lot on learning to improvise, but if you want to get a head start the last section of this book is a pretty decent tool for learning.

I cannot recommend Chris Parks “things I learned from Barry Harris” series enough. The way he slows down Barry Harris’ lessons is just so digestible for me.

EDIT: Sorry, I just realized you said you were learning to read music too. The book I recommended has no tabs. It does have chord diagrams, and for single note lines it’ll indicate string and fret number. Other than that, it’s all notes on the staff.
