How do you raise the action on a Gibson SG?
Checklist: Changing the action
- Get your guitar into pitch.
- Take the ruler and place it on the 12th fret, measuring from fret to string.
- Measure the height on the low E string and the high E string.
- Based on your factory specs, or the basic measurements in the text above, decide if you need to go up or down on either side.
