EMG-KH20. Kirk Hammet Prewired pickguard.
Kirk Hammett visited EMG for the first time in the early 80's when Metallica was a local group on the way to success. The KH20 set combines an EMG-81 with a pair of EMG-S single coils.
These microphones are built around a pair of ceramic magnets to provide a coherent and controlled sound. They are connected to a master volume and a master tone and mounted on a white pearl imitation pickguard with black knobs.
