Independent shopping perspective
The Korena take
NUX’s MG-400 combines guitar, bass, and acoustic-amp processing in a compact black pedal. Its 25 guitar-amp emulations sit alongside one bass amp and one acoustic-amp simulation, with movable signal blocks for building chains in the order you choose. Cabinet options include onboard guitar and bass selections, acoustic-guitar IRs, and third-party IR loading through QuickTone. A color LCD handles parameter editing, while drum loops, a tuner, looping, and USB recording-interface capability extend the unit beyond its core effects processing.
Strong match
Who this is for
- Building adjustable guitar, bass, or acoustic-guitar signal chains with freely movable amp and effect blocks.
- Solo practice or songwriting with onboard drum loops and a 30-second stereo or 60-second mono looper.
- Recording through USB while using the MG-400 as a recording interface.
Consider the trade-offs
When to look elsewhere
- Looping needs that exceed 30 seconds in stereo or 60 seconds in mono.
