Kirk Hammett first visited EMG back in the early '80s when Metallica was a local group on the rise. The KH20 system joins the EMG-81 with a pair of EMG-S single-coil pickups. These pickups are all built around ceramic magnets for the tightest, most controlled sound. They're mated with a five-position switch and master volume and tone controls. The KH20 comes pre-assembled on a custom Pearl White pickguard with contrasting black knobs.Package Includes: Prewired to the specifications of each artist. Complete and ready to mount to your guitar.
