Packed with a full range of effects for limitless creativity.
We've all experienced digital pre-effect pedals that belong on the Wall of Shame - especially Overdrive. Modelers of this kind used the linear algorithm which doesn't provide negative-feedback for dynamic playability. Enter the NUX MG-300 MKII, the modeler that will totally blow your mind! The pre-effect block beautifully recreates the awesome signature sound of real analog overdrive / distortion pedals.

The MG-300MKII also includes a special Patch Level (P.L) block. You can place it anywhere in your effect routing and adjust the level through it.

TSAC-HD - WHITE-BOX Amp Modeling Algorithm
What is the most important component in an Amp Modeler?
In 2010 NUX introduced TSAC (True Simulation fo 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 AX-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 analogue 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, with a straightforward high-performance algorithm to not only fit this specific DSP platform, but dominate the multi-efx platform in general.

Impulse Response for Cabinet Simulation
36 built-in IRs, 24 user-loadable slots, with individual parameters setting for each.

The NUX MG-300 MKII offers advanced Impulse Responses (IRs) for authentic tone reproduction. It features 25 guitar cab IRs, 8 bass cab IRs, and 3 acoustic IRs, capturing the essence of real-world counterparts from vintage warmth to modern clarity. With 4 microphone models, 3 mic positions, you can shape your sound precisely.

Seamlessly integrated with the MG-300 MKII's amp modeling and effects, these IRs provide an immersive experience, delivering legendary amplifier realism on stage, in the studio, or during practice. The NUX MG-300 MKII also includes 24 user-loadable IR slots, allowing you to import and save your own Impulse Responses. This feature offers extensive customization, letting create unique and more personalized tones.

Each IR can be individually adjusted with LEVEL, HIGH-CUT, and LOW-CUT controls, giving you complete control over your sound.

Fully Customizable Signal Block Routing
Freely position effects and amp blocks in any order, providing unprecedented control over your signal chain.

Jam Mode (Drum & Looper)
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.

Choose between STEREO (60 seconds) or MONO (120 seconds) looping to suit your needs.

Comprehensive and Powerful I/O Capabilities
For studio, stage and streaming.

Full Editing Control with the QuickTone™ Editor Software
The NUX MG-300 MKII comes with the powerful QuickTone software editor, designed for intuitive sound customization. This newly designed user-friendly interface allows you to easily tweak parameters, reorder effect blocks, and manage your patches. With QuickTone, you can import and save your own Impulse Responses, organize Pro Scenes, and configure USB routing with ease. Whether you're fine-tuning your tone or exploring new soundscapes, QuickTone gives you the control and flexibility to shape your perfect sound.

Tweakable Footswitch
The MG-300 MKII introduces a tweakable footswitch setup, allowing you to fully customize your footswitch configuration. Preset Up and Down: Simplify preset navigation, allowing quick switches between presets. Scene Up and Down: Navigate through three scenes within a preset for layered sound changes. Scene Down and Preset Up: This hybrid setting lets you access different presets while managing scenes within them. Additionally, you can deactivate Scene 3 for straightforward A/B sound switching between Scene 1 (S1) and Scene 2 (S2).

The MG-300 MKII also upgrades the expression pedal switch. Compared to the previous version, it now features a physical Toe Switch, offering more convenience and a clear 'switching feel'. And there's no need for 'expression pedal calibration' anymore. The Expression Pedal can be used to control the volume or the effects.

Detailed instructions on how to assign functions and how to calibrate the pedal are provided in the User Manual.

Perfect for Live Performances: Pro Scene Selection
Navigate through three distinct scenes within a single preset, each offering a unique sound configuration. With the Pro Scene Selection feature, you can change effects models, amp models, settings, and more, all within the same preset.

This capability is ideal for live performances where quick sound changes are crucial, allowing you to switch seamlessly between different tones and setups. Whether you need a clean sound for verses, a crunchy tone for choruses, or a lead boost for solos, Pro Scene Selection ensures that you're always ready with the perfect sound at the tap of a footswitch.

Real-Time Output Adjustment
Adjust your output in real-time with the NUX MG-300 MKII's intuitive controls. Use Knob 1 to fine-tune the phones output and Knob 2 to manage the main output. Whether you're on stage, in the studio, or practicing at home, these easy-to-access knobs ensure your sound is always perfectly balanced.
