All your essential tones in one compact floor rig (gig-ready, studio-ready, practice-ready)
The NUX MG-300 is built for guitarists who want inspiring amp-and-effects tones without hauling an amp stack or building a massive pedalboard. It delivers realistic feel (not just "pretty sounds") thanks to NUX TSAC-HD amp modeling, then finishes it off with studio-quality Core-Image post effects. Add IR cabinet simulation, USB recording with re-amp, and a drum + looper setup that actually helps you practice and create, and youve got a do-it-all multi-FX that punches way above its size and price.
Features
- TSAC-HD amp modeling and pre-effects feel: Designed for responsive, amp-like playability and touch dynamics.
- Core-Image post effects: Studio-style modulation, delay, and reverb options that sound polished and musical.
- IR cabinet simulation: 512-sample IR resolution, 25 built-in cabinet IRs with 4 mic types and 3 mic positions, plus 12 user-loadable IR slots (48kHz WAV supported).
- USB audio interface with re-amp: Record direct to your computer and re-amp for fast, flexible tracking and tone decisions.
- Phrase looper + drums that stay locked: 60 seconds of looping, plus 56 drum beats (8 styles with 7 beats each) with phrase loop sync for tight practice and writing.
- Global 3-band EQ: Quick tonal tweaks for different rooms, stages, and speakers without rebuilding every preset.
- Expression pedal control: Assign it to volume or effect parameters (wah, drive, mod mix, delay mix, reverb mix, and more).
- 5 output modes: Optimized routing for direct-to-PA/interface, or into combo/stack front input or FX return.
Advantages
- Show up with one piece of gear: Great tones, effects, cab sim, and practice tools in a single compact unit.
- Consistent sound anywhere: Dial in a tone you love, then keep it consistent across gigs, rehearsal rooms, and recording sessions.
- Faster workflow: USB recording + QuickTone editing makes it easy to tweak, save, and refine tones without menu fatigue.
Benefits
- Play more, troubleshoot less: Fewer cables, fewer pedals, fewer "why does my rig sound different tonight?" moments.
- Practice that actually improves your timing: The synced looper and rhythm patterns make it easy to build tight parts and progress faster.
- Record-ready tones at home: IR cab sim and USB audio help you capture polished tracks without miking a cabinet.
