kirk hammett first visited emg back in the early 80’s when metallica was a local group on the rise. this system is a simple emg-81/ 81 combination wired straight up with two volumes and a master tone. lean and mean. the sheer volume and amount of sound coming from the metallica stage is incredible. the demands made on every piece of gear are extreme, it’s no wonder kirk has come to rely on emg. the kh21 features a pearl laminate pickguard complimented with black dome knobs.81/81 black 2 volume & 1 tone pot white pearl pickguard black knobs kirk hammett.
