I have been playing 5 months and I can't name let alone play any scales so what are some I should learn?
The pentatonic is pretty easy to learn, the blues pentatonic (not sure wat its called), and major and minor scales. That should start you off
Look into the book "Total scales techniques and applications" by Mark John Sternal.It's packed with info on a ton of scales and was a great tool for me when I was just starting out.
You should post this in the "Guitar Techniques" forum, you will get better help there.
