Everything you need, and more

The MG-300MKII retains all the beloved effects of the MG-300, delivering everything from rich overdrives and dynamic compressors to lush delays, expansive reverbs, and precise EQs. With a comprehensive selection that includes 1 Noise Gate, 2 COMPs, 13 OD/DISTs, 1 Touch Wah, 2 EQs, 14MODs, 7 DLYs, 5 RVBs, this unit has it all.

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.

What sets the MG-300MKII apart is the addition of the new Shimmer Reverb. Elevate your sonic palette with this ethereal effect, perfect for creating spacious, atmospheric soundscapes that add a whole new dimension to your music.

Unlock More Tones with Block Switching

In the EDIT mode, you can switch the function of CMP, EFX, or RVB by long-pressing the block, opening up endless creative possibilities for crafting your perfect tone.

CMP -> EFX

You can stack dual OD/DIST effects for a heavier distortion or set one of the EFX to a Boost to add more saturation to the overdrive.

EFX -> MOD

Combine the Octave effect with the Rotary effect to create a unique organ-like tone, perfect for adding texture to your sound.

RVB -> DLY

Stack dual Delay effects to create more complex and interesting tones, ideal for ambient or experimental styles.

TS/AC-HD
WHITE-BOX Modeling Algorithm
What is the most important component in an Amp Modeler?

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, with a straightforward high-performance algorithm to not only fit this specific DSP platform, but dominate the multi-efx platform in general.

Impulse Responses
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.

JAM Mode

Looper and Drum Machine

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.

Ultimate Flexibility

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

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.

Comprehensive and Powerful I/O Capabilities

For Studio, Stage, and Streaming

The MG-300 MKII features modernized connectivity to meet the needs of today’s musicians. It comes equipped with a USB-C port for smooth integration with music production software and an enhanced TRRS-supported Phones jack, perfect for headphones with built-in microphones.

For live streaming, the TRRS jack and USB-OTG compatibility make it easy to connect to smartphones. Fine-tune your sound with dedicated microphone level controls and a built-in noise gate for clear, professional audio delivery.
