NUX METAL CORE DELUXE MKII – guitar preamp with three iconic hi-gain amp simulations The NUX METAL CORE DELUXE MKII is a compact pedal-format preamp designed for guitarists who seek powerful, modern metal and rock tones. With three simulations of legendary amplifiers – Duo Rect, Fireman, and VH4 – it delivers a wide palette of sounds, ranging from classic American metal to British rock and contemporary studio tones.

Product features 3 hi-gain amp simulations: Mesa Boogie Dual Rectifier, Friedman BE-100, and Diezel VH4.

USB-C port for parameter editing, custom IR loading, and firmware updates.

Support for IRs up to 512 samples resolution.

Mobile EFX app support (iOS/Android) via OTG connection.

Compact, durable design with low power consumption (under 120 mA).

True-bypass and automatic parameter saving.

Maximum tonal freedom Thanks to TSAC-HD technology, the METAL CORE DELUXE MKII pedal realistically reproduces tube amp dynamics and response. Each amp simulation comes with a dedicated IR that complements its character, while the ability to load custom third-party cabinet impulses makes it highly versatile. This flexibility ensures players can shape their tone to suit any genre or style.

Applications This pedal is perfect for both live performance and studio recording. With IR output, it can be used without a traditional amp – simply connect it to an audio interface or PA system. It’s an ideal solution for metal, hard rock, and alternative guitarists who want access to aggressive and dynamic tones at their feet.
