I had a string break when I was changing a set of Blue Steel strings on my Acoustic. Threw Some Ernie Ball Super Slinky (11-52) on there with no problem. They are classified as a custom gauge light, Extra Slinky's are Extra Light.
The electric has D'Addario XL's. I just checked, and they are 10-46's. I can do basic things like changing strings, but I don't think I want to mess up the intonation. :) Is there a good tutorial on doing this, as well as adjusting the bridge?
