TS/AC-HD WHITE-BOX Modeling Algorithm

In 2010 NUX introduced TSAC (True Simulation of Analog Circuit) with the sole intention of bringing Amp Modeling to a whole new level. The DSP industry has been evolving at breakneck speed, and keeping up can be a challenge. We were impressed that a product like the Fractal® AXE-FX had the foresight to use a high-definition TSAC (white-box) algorithm to do its Amp Modeling. So we took note and started development on an affordable modeler with TSAC-HD.

The concept of “Chaos makes the muse” perfectly applies to the analog circuit. When you tweak the knob, it affects itself as well as other parameters. For a linear digital system, the parameter is independent. The white-box algorithm offers real negative-feedback, increment-by-increment. NUX TSAC-HD replicates the same playability most guitarists prefer in a real tube amplifier.

Building a sky-high priced product is easy. The art of building an affordable product is a real challenge. We priced the MG-300 MKII, with a straightforward high-performance algorithm to not only fit this specific DSP platform, but dominate the multi-efx platform in general.

JAM Mode

The NUX MG-300 MKII expands your musical creativity with its integrated Phrase Looper and versatile drum machine. The Phrase Looper allows you to layer guitar lines effortlessly, creating rich, textured sounds perfect for solo performances or songwriting. The drum machine, equipped with auto tempo detection, synchronizes its rhythm to match your playing speed, enhancing both practice sessions and live performances with seamless, cohesive rhythms.
