The NUX MG-50Li is a flagship multi-effects processor for guitar and bass that combines traditional physical modeling with advanced amp profiling. It is unique for featuring a built-in rechargeable lithium-ion battery, allowing for up to 5–6 hours of wireless performance. Key Performance Technologies DeepImage Modeling & Profiling: This proprietary black-box technology allows you to capture and store ultra-realistic profiles of your own amps, preamps, and drive pedals. It also supports external NAM (Neural Amp Modeler) files. TS/AC-4K White-Box Modeling: An evolution of NUX’s modeling algorithm that is twice as intricate as previous versions, delivering highly realistic tube amp feel and dynamic response. Triple-DSP Architecture: Uses three dedicated NXP RT processors—one for effects, one for amp modeling, and a third for split-amp s ...
