Thrash metal is visceral, energetic, aggressive. Getting the right depth and texture of sound, the right bite in the attack, the right snarl on the tail, is essential. You need an amp like a wild animal, like a fighter, like a beast. Kerry King has spent four decades at the vanguard of the scene, blazing trails and busting guts with his edgy in-your-face sound, so naturally his signature amp – the custom Marshall 2203KK, a.k.a. “The Beast” – is the only place to start if you’re after super high gain and punchy articulation in a single rig.
