NUX MG-400 Multi Effects Guitar Pedal Amp Modeling and USB recording interface (Open Box like new)

Amp Modeling Algorithm for easy Tone TweakingThe White-box Amp Modeling & Pre-Efx algorithm offers realistic playability and analog-chaos response.The concept of "Chaos makes the muse" perfectly applies to the analogue circuit. When you tweak the knob, it affects itself as well as other parameters. For a linear digital system, the parameter is independent. The white-box algorithm offers real-time feedback, increment-by-increment. NUX TS/AC-HD replicates the same playability most guitarists crave in a real tube amplifier.2 Powerful DSP Chips for High-DefinitionMG-400 houses 2 powerful DSP chips for high-definition White-Box Amp Modeling algorithm (TS/AC-HD) and Core-Image post-effects. MG-400 sets moveable signal blocks, 12 IR COLLECTION slots, flexible P.L block with MIN & MAX parameter setup, abundant SYSTEM MENU, and physical MASTER volume knob.512 Samples IR Resolution and USER slot with each patchMG-400 includes multiple impulse response of 512 samples each. You can load 3rd party IR files using our NUX QuickTone edit software (support up to 48kHz sample rate). The included 25 guitar cabinet IRs combine 4 classic microphones with 3 mic positions to allow beginners a quick and easy way to jump into the multi effects experience. Also included are 8 bass cabinet IRs and 3 acoustic guitar IRs, giving you the ability to play bass guitar on MG-400 or use electric guitar to simulate acoustic guitar sound with acoustic guitar IRs.10 Independent Flexible BlockNG, CMP, EFX, AMP, IR, EQ, MOD, DLY, RVB, P.L / 10 independent moveable signal blocks.You can move signal blocks freely on the MG-400 and/or QuickTone editing software. Set the PATCH LEVEL block in front of AMP to swell the volume. Put DELAY block in front of gain stage to create grooving riffs. There are lots of tone creations with the flexible block routing.Use SCENES to engage/disengage blocks with either CTRL footswitchYou can assign CTRL1 or CTRL2 to trigger the SCENE Functionality. Each preset has 3 scenes, which are snapshots within a preset. This is a powerful function for live gigs. Each SCENE can engage/disengage signal blocks freely, and it retains the DELAY / REVERB trails when you disengage them with SCN CTRL.Jam ( Drum & Looper )MG-400 supports NUX Phrase Loop Synchronization with Rhythm. You can play the rhythm then record your phrase loop. MG-400 will automatically beat match the phrase to fit the current rhythm BPM.Choose either STEREO / MONO looping. (Stereo is 30 seconds, mono is 60 seconds.)Two Recording ModesNR = Normal Recording works as regular loop function, while you press CTRL1(LOOP) footswitch, it starts to record the phrase loop.AR = Auto Recording will stand by while you press CTRL1(LOOP) footswitch, once you hit the strings, it will start to record your phrase loop.
