Bringing together a three-knob control scheme for drive, tone, and volume and a whopping five switches for minutely altering low and high EQ, body, and compression styles, the KHDK Electronics Kirk Hammett Signature Ghoul Screamer Handmade Overdrive is a culmination of effects styles in one stomp box. Able to jump from a tube-like warmth to a searing gain-laden shriek, this may be the last overdrive you'll ever need.
