Using this 0.125 - inch thin EMG Flat 7 pickup mounting ring is easy. First, make sure your guitar is turned off. Then, remove the old mounting ring if there is one. Place this new ring in the neck position where it's designed to fit. It directly replaces standard seven - string humbucking pickups. When you're done, turn your guitar back on and test it out. As for maintenance, keep it clean. Wipe it gently with a soft cloth to prevent dust build - up. Avoid using harsh chemicals as they may damage the ring. If you notice any issues, check the fit and connections to make sure everything is secure.
