Product Description
The NUX MG-300 packs studio-grade tone and performance tools into a pedalboard-friendly housing. Powered by a 32-bit DSP with 24-bit/48 kHz AD/DA conversion, it delivers 25 amp/cab models and over 40 high-quality effects including overdrives, distortions, modulation, delays, and reverbs. Onboard drum machine and 60 s phrase looper fuel practice and songwriting, while the built-in expression pedal gives you hands-on control over wah, volume, or any effect parameter.
Load custom cabinet impulses via the IR loader for ultra-realistic speaker simulation, then connect to your PC or Mac over USB for 2-in/2-out audio-interface functionality. Dual power options (9 V DC or AA batteries) mean you can gig, rehearse, or record anywhere without compromise.
