MG-50Li

Classic Tones, Defined by You

The MG-50Li stands as NUX’s flagship multi-effects processor for guitar and bass, a formidable fusion of two core technologies: TS/AC-4K white-box physical modeling amps and DeepImage profiling amp models. Its streamlined design, intuitive interface, and pristine tones invite players into a realm of sonic exploration. Encased in aluminum alloy, featuring six robust footswitches and a high-definition LCD, the MG-50Li is a timeless instrument, ready for any stage or studio. Crafting your signature sound has never been more fluid.

Authentic Tube Amp Experience

At the core of the MG-50Li lies our iconic TS/AC-4K Amp Modeling (White-box Physical Modeling algorithm), now twice as intricate as its predecessors. This engineering feat necessitated a new hardware platform, housing three dedicated DSPs: one for effects, one for amp modeling, and a third for split amp simulation. We’ve dissected amp modeling into distinct preamp and power amp simulations, granting you the power to sculpt unique sonic textures by interchanging power tube models.

With DeepImage, guitarists can imprint their dream amps directly into the MG-50Li, carrying their sonic arsenal wherever inspiration strikes.

L/R Cyber IR: Realistic Space

The MG-50Li integrates Cyber IR™ Technology – a true impulse response reproduction driven by an advanced algorithm. This empowers precise adjustments for Microphone type, Position, and Distance, offering stereo IR capabilities with imperceptible latency. Sculpt your acoustic space with surgical precision.

Flexible Routing: Dual-Chain & 14 Effect Blocks

Unleash boundless tonal architectures with up to 14 simultaneous effect blocks and an ultra-flexible dual-chain routing system. The MG-50Li transforms into your personal sonic laboratory, allowing musicians to freely customize the effects chain to forge their ultimate tones.

Audio Clarity, Millisecond Response

Driven by three powerful NXP® RT processors and premium 32-bit AD/DA converters, the MG-50Li delivers unblemished sound quality with ultra-low system latency. Experience a tight, fast response that translates every nuance of your playing.

Stage Lineage, Battle-Ready

Engineered for the demands of live performance, the MG-50Li features professional-grade I/Os: two effect loops for integrating your cherished pedals, stereo XLR outputs for direct mixer integration, and MIDI in/out for seamless command over your MIDI ecosystem.

6 Hours Endurance: Unbound Freedom

Designed for liberation, the MG-50Li incorporates a built-in battery, granting you the power to perform anywhere, anytime, unburdened by power outlets. Simply plug in and play – your stage is wherever you are.
