Randall RM100KH Amplifier Head w/ KH1, KH2 & KH3  Preamps + Mercury Transformer

Upgraded with Mercury Magnetics Transformer

A Sonic Tribute to Kirk Hammett’s Iconic Tone

The Randall RM100KH is a 100-watt, all-tube modular amplifier head developed in collaboration with Kirk Hammettand George Lynch, designed to deliver the full range of Kirk’s legendary tones in a single, flexible platform. Built around Randall’s Modular Tube System (MTS), this amp offers authentic tube response with exceptional depth, clarity, and punch.

This unit has been upgraded with a Mercury Magnetics transformer, a highly regarded aftermarket upgrade known for improving harmonic richness, low-end authority, and overall dynamic response—bringing even more life and dimension to the amp’s already powerful tone.

Equipped with three Kirk Hammett–voiced modular preamps, the RM100KH covers everything from pristine cleans to classic thrash rhythms and modern high-gain lead tones—making it equally at home on stage or in the studio.
