NUX Metal Core Deluxe MKII Preamp Pedal

The NUX METAL CORE DELUXE MKII is a high gain preamp pedal with 3 distinctive high gain amp models including the Duo Rect, Fireman, and VH 4. You can select these models via the 3-way toggle switch.

The NUX Metal Core Deluxe MKII packs the power of three legendary amp heads into one compact, road-ready pedal. This high-gain preamp offers the tones of classic heavy, hard rock, and metal — everything from tight, aggressive distortion to thick, saturated wall-of-sound tones.

With three selectable amp models (Duo Rect, Fireman, and VH4), you can recreate the iconic sounds of ‘90s American metal, British hard rock, or modern crushing metal tones, all from a single stompbox. Each amp model comes with a matching cabinet simulation (IR), and you can load your own third-party IRs to tailor the sound exactly how you like it.

Whether you’re playing live with a FRFR system, practicing silently with headphones, or recording directly — Metal Core Deluxe MKII gives you studio-grade, high-gain tones without the need for a full amplifier stack. Its TSAC-HD amp modeling delivers realistic amplifier feel and response under your fingers.
