NUX NU-X MG-300MKII Guitar Modeling Processor

Nux MG300MKII Guitar Modelling Processor Multi-Effects Pedal
The NUX MG-300MKII is a feature-packed multi-effects processor that delivers exceptional sound quality, intuitive control, and professional versatility at an unbeatable price. Building on the foundation of the popular MG-300, this upgraded MKII model brings a range of improvements that make it even more powerful and flexible for guitarists of all levels.

At the core of the MG-300MKII is NUX’s renowned TSAC-HD (True Simulation of Analog Circuit) modelling engine. This technology faithfully recreates the sound and feel of tube amplifiers, offering dynamic response, touch sensitivity, and authentic tone across a wide range of amp models. Paired with high-resolution IR (impulse response) cabinet simulation, the result is a realistic and inspiring playing experience, whether you’re practicing through headphones, recording directly, or playing through a PA system.

The MG-300MKII features a larger and clearer LCD screen than the original model, making it easier to navigate menus, adjust parameters, and manage presets. The upgraded user interface is clean and responsive, allowing for quick edits on the go without breaking your creative flow. The unit also includes expanded input and output options, offering greater flexibility when integrating into different setups. Whether you’re connecting to an amp, mixer, audio interface, or using headphones, the MG-300MKII adapts to your environment with ease.

Latency has been further reduced in the MKII, providing an ultra-responsive playing feel that keeps up with your performance. You’ll notice tighter timing, especially when playing fast or rhythmically complex parts. This is particularly valuable when using the MG-300MKII in a live setting or while tracking in the studio.

A standout new feature is the Pro Scene mode, which allows multiple parameter and effect changes within a single preset. This means you can switch between clean, rhythm, and lead tones or activate multiple effects simultaneously with a single footswitch press, giving you more control and creative freedom during performances.

The MG-300MKII also greatly expands its impulse response support. While the original MG-300 had limited IR capacity, the MKII now offers 24 user IR slots, allowing you to load third-party cabinet simulations and acoustic impulse responses. This opens up a huge range of tone-shaping possibilities and lets you customise your sound in detail.

One of the most exciting additions is the new Shimmer Reverb effect. This ambient reverb adds a lush, ethereal quality to your sound, perfect for ambient, post-rock, worship, or cinematic styles. It’s a creative tool that adds a new dimension to your tone and helps your playing stand out.

For recording and streaming, the MG-300MKII includes USB audio interface functionality, allowing you to record directly to your computer with no need for additional hardware. This makes it a great all-in-one solution for home studios, demo creation, or content production.
