Some electric guitars and basses produce unwanted noises mostly caused by external sources. This occurs mostly in guitars with single coil pick-ups. You can help reduce these unwanted noised by shielding the electronics cavities inside your instrument by applying copper tape or conductive shielding paint. 

This conductive shielding paint:

• Helps reduce unwanted noises
• Protects the cavities of your instrument
• Is easy to apply
• Is water-based and friendly for the environment
• Is enough for 5 to 10 guitars
