How can I determine if the truss rod in my guitar is broken?

To determine if the truss rod in your guitar is broken, you can visually inspect the neck for any unusual bending or warping. You can also try adjusting the truss rod to see if it responds properly. If the neck remains bowed or twisted after adjustments, it may indicate a broken truss rod. It is recommended to consult a professional guitar technician for a more accurate assessment.
