I was just wondering, I found a review on a Fender Tele, and someone used the following phrasing, "Setup wasn't perfect (but who uses 9s on a tele anyway?). Did the setup and put on 11s and its spot on now..." Can anyone tell me what 9's and 11's refers to??
The gauge (thickness) of the strings.
9s are a light gauge, whereas 11s are considerable heavier. Typically, light strings have reduced tension, making bending easier. On the other hand, many people prefer the thicker tone of higher gauges
