While the theory is obviously the same, the approach to learning sax is very different than guitar. I've played guitar for 30 years. Everyday since I started playing sax about 6 years ago I realize more I need to stop thinking like a guitarist when playing sax. Guitar technic is focused first on the faculty of your hands. Sax technic is focused on your lungs, throat, tongue, lips, and lastly your hands. Books written by sax/wind players will offer challenges and exercises meant to improve what a sax player needs to work on first. Really, you'll learn more about playing guitar from a sax oriented instruction book than the other way around IMO.
Also, don't waist time and frustration. Get a teacher. Good luck.
