NUX MG-300 Modeling Guitar Processor

The NUX MG-300 is a guitar effects processor designed to offer high-end sound quality in a space-conscious format. Combining TSAC-HD pre-effects and amp modeling with Core-Image post-effects, it replicates the feel of real analog gear, while providing flexibility through impulse response (IR) loading and an intuitive user interface. Whether you're gigging, recording, or practicing, the MG-300 delivers powerful, studio-grade sounds without the hefty price tag. With its ability to load third-party IRs, sync with rhythm tracks, and access a rich library of modulation effects, this processor is a solid companion for musicians of all styles.

TSAC-HD Pre-Effects & Amp Modeling

The NUX MG-300 is built on TSAC-HD (True Simulation of Analog Circuit) technology, replicating the natural dynamics and feedback responses of analog amplifiers. This high-definition pre-effects and amp modeling ensures that every adjustment to your tone feels immediate and organic, providing the depth and playability guitarists crave. Unlike traditional digital models, the MG-300 incorporates real-time, incremental feedback, ensuring an experience more akin to tweaking a tube amp.

Impulse Response & Core-Image Post-Effects

The MG-300 offers a 512-sample resolution for its built-in impulse responses (IRs), delivering highly detailed cabinet simulations. It also allows users to load third-party IRs using the NUX QuickTone Edit Software, expanding tonal possibilities. Along with this, Core-Image post-effects provide studio-quality sound shaping, offering a broad range of classic modulation, delay, reverb, and more

Phrase Looper with Auto Rhythm Sync

The MG-300 includes an advanced phrase looper that synchronizes with rhythm tracks, allowing guitarists to create layered performances with ease. With 60 seconds of loop recording time and 56 drum beats across 8 rhythm styles, this feature enables both practice and live performance versatility. Whether you're building complex layers or jamming to a rhythm track, the MG-300's looper and drum machine integration will keep your creativity flowing.

Why We Love It
