The NUX MG-100 is a budget guitar multi-effects processor released in 2011. It comes packed with a colorful LED display, an assignable expression pedal, a 40-second looper, a drum machine, tap tempo, and a chromatic tuner, and runs on 6 AA batteries (sold separately) for up to 8 hours, or a power adapter (included).
The MG-100 offers 36 factory presets and 36 slots for user-created ones, plus a total of 58 guitar effects, including 13 amp and 11 cabinet models, arranged into 8 modules, which can be used simultaneously. However, the modules themselves – and therefore similar effects – cannot be stacked.
It has jacks for 1/4″ input and output as well as an auxiliary port for headphones or a CD/MP3 player. The processor is contained in a solid steel housing with plastic knobs and other elements, which seem sturdy as well
