The NUX Mighty Plug Pro (MP-3) is a pocket-sized, ultra-portable headphone amp and modeler that turns any guitar or bass into a silent practice powerhouse, recording tool, or even livestream rig—perfect for players who need quiet sessions in flats, travel light, or want pro tones on the go without a full amp setup.
This little beast plugs directly into your instrument's output jack (rotating 1/4" plug for flexible positioning), then feeds your headphones (3.5mm stereo mini jack) with realistic amp modeling, effects, and IR cabinets—all powered by NUX's TSAC-HD White-Box Modeling algorithm for natural tube-like dynamics, real-time feedback, and ultra-low 1.2ms latency. It supports both guitar and bass modes, plus acoustic guitar simulation via IRs for versatile use.
Modeling and effects highlights:
- 29 amp models (electric guitar, bass, and acoustic sims) covering classics like Fender cleans, Marshall crunch, Mesa high-gain, and more—delivering authentic feel and playability.
- 34 IRs (512-sample resolution): 36 premium built-in cabinet simulations (guitar, bass, acoustic) + 18 user slots for loading third-party IRs to match your guitar/pickup or favorite cabs/mics.
