2. Checking Your Guitar Neck
While setting up the neck of your guitar may seem like an intimidating task, it’s actually fairly simple.
To start, take a close look at the neck. You can do this in a few different ways. I like to sight my guitar by holding it up and using the body of the guitar as a reference frame.
Does it look straight? Is the back bowed in any way?
Are the strings touching the frets in the middle? Or maybe they’re touching the frets everywhere but the middle?
If you can see that the neck isn’t straight, you need to adjust the truss rod. The truss rod is a long metal rod that goes through the whole length of your guitar’s neck.
You can usually access the truss rod on the top of your neck, at the point where it meets the head with the tuning mechanism.
However, there are few different designs out there. A quick look-up of your specific model may sometimes be required.
Note -
If you are looking to make micro adjustment, you’re going to need an action gauge. Follow this guide here. The access point at the top of the neck is usually covered by a piece of plastic, so move that out of the way. Now, take the matching Allen key, and insert it.
• If the neck bows away from the strings, you need to tighten the truss rod
• If it bows towards the strings, you need to loosen the truss rod
Every time you turn the Allen key, do it a step at a time. Don’t turn it in full circles, as you will overdo it. Continue to make gradual adjustments until your neck is brought back into alignment.
If it doesn’t turn smoothly – stop! Never force a truss rod. This is usually a symptom of a larger problem. Don’t worry too much if the neck wasn’t straight.
This tends to happen over time, due to the differences in temperature, humidity, and general use. Just make sure that you check if the neck is straight from time to time.
Your guitar will thank you!
