Blends with a black pickguard or a dark body. Stands out against white or tortoise.

Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Traditionally between the neck and the pickup. Older basses placed it below the strings; most players now mount it above for fingerstyle anchoring.
It is sized for Precision and Jazz Bass. Other basses may work, but the screw holes likely will not line up.
Check the package before installing. Plan on sourcing correctly sized screws so you do not split the pickguard.
Not securely. It is designed to be screwed into the pickguard or body, and adhesive will not hold under thumb pressure.
