The NUX Metal Core Deluxe features three separate amp models, each based on a giant in the world of METAL.

Although there are many great sounds in here, we are instantly sent back to the '90s by selecting "Duo Rect", cutting the mids and maxing everything else!

There are also some secret functions but we think NUX have said it best:

"Evolving from the popular Metal Core Deluxe pedal, the mkII version now has 3 selectable amplifier models based on much-revered high gain valve amplifiers. Now with an additional Middle control, the 3-band EQ pairs with Gain and Master to offer a full completement of real amplifier controls, with settings stored into each of the 3 amp models for fast recall. Metal Core Deluxe mkII goes a step further to include IR cabinet simulation, meaning that it can be used directly into a full-range PA system, or without IR simulation into the front of a guitar amplifier as a hard-edged drive pedal."
