The NUX MG-30 (Versatile Modeler) is a powerful, compact multi-effects and amp modeling floor unit that's a step up from entry-level options like the MG-101—offering pro-level tone, deeper editing, and live-ready features in a rugged, gig-friendly package. It's widely regarded as one of the best value modelers, punching way above its weight with realistic amp feel, massive IR flexibility, and versatile connectivity for recording at home, practicing silently, or hitting local venues/stages.
An evolution of the popular MG-300, the MG-30 upgrades to dual NXP RT processors and refined TSAC-HD White-Box Modeling (now at 2K definition) for ultra-realistic tube amp dynamics, touch-sensitivity, harmonic richness, and ultra-low latency (~1-2ms typical in reviews). It delivers ~110dB dynamic range and premium 32-bit/2-channel AD/DA converters for clean, high-headroom sound that rivals pricier units.
Core modeling power:
- 30 amp models — 25 electric (vintage Fender cleans, Marshall plexi, Mesa/Rectifier high-gain, boutique moderns), 3 bass amps, 2 acoustic sims.
- Impulse Response (IR) system — 1024-sample resolution stock cabs (23+ built-in), 8 mic types, 3 mic positions per cab, plus 12 user-loadable IR slots (some sources note up to 32x4 in expanded modes) for third-party IRs and endless cab/mic combos.
- 56+ effect modules across 11 flexible signal blocks (movable routing): noise gate, compressors (3 types), drives/distortions (14+), EQs (4), modulations (13 like chorus, flanger, phaser, Uni-Vibe), delays (8), reverbs (5), wahs, and more—totaling 70+ effects in some listings.
Standout practical features:
- Large 4" colorful LCD screen + intuitive 5-way encoder for fast, menu-free editing—no manual diving needed.
- Built-in expression pedal for real-time control (volume, wah, whammy, etc.).
- Looper (phrase recording with overdub) + drum machine for practice/jamming.
- USB audio interface (multi-channel) for direct DAW recording, reamping, firmware updates, and QuickTone™ editor software (PC/Mac; GEN2 firmware compatible).
- Stereo/mono outs, headphone jack, AUX in, send/return effects loop, MIDI in/out, and balanced XLR outs for direct-to-PA or interface use.
- Global 3-band EQ, patch/scene management, and quick bypass/engage per block.
Tech specs highlights:
- Processing: 48kHz/32-bit with huge headroom.
- Power: 9V DC (center-negative, ~400mA draw) — pedalboard-friendly.
- Compact, durable build (metal chassis) with included NMP-2 external footswitch for extra control (bank up/down, scenes).
- Supports guitar, bass, and acoustic inputs for multi-instrument versatility.
Compared to the MG-101 (your entry-level brother), the MG-30 steps up with dual processors for better definition/response, larger screen, more advanced routing/IR slots, expression pedal, effects loop, MIDI, and overall pro features—making it ideal for gigging or serious home/recording use while staying compact and affordable. Reviews and demos (2025–2026) frequently call it a "flagship" in the MG series for its realism, low latency, and value—great for stacking with your NUX minis (Horseman, Voodoo Vibe, Komp Core) on a Bumblebee board or going fully modeler with wireless (B-5/C-5) freedom.
