Using this EMG DG20 pickguard set is easy. First, take out the set from the box. Since it's prewired with EMG's solderless install system, you don't need to worry about soldering. Just mount it on your guitar following the standard pickguard installation steps. When you start playing, you'll notice the improved treble and bass frequencies thanks to the EXG Guitar Expander. The SPC presence control can be adjusted to your preference to get the best mid - range and earthy tones. As for maintenance, keep your guitar in a dry and clean place. Wipe the pickguard gently with a soft cloth after each use to prevent dust and dirt build - up. Avoid exposing it to extreme temperatures or humidity as it may affect the performance of the pickups.
