I really like it, basically an RC3 without the Boss baggage/cost. Same 16 bit processing rate as an RC3, same single switching control (unless you get a 2 button footswitch and TRS cable) but even a 2 button footswitch that isn't BOSS costs less, so you aren't getting anything more, really, with the Boss and actually you are saving money after buying a footswitch for added control with this one.A note about my setup. I use a wireless guitar system, virtual amps, physical amp, and both virtual and physical pedals, mostly in a home case scenario, though I can duplicate it somewhat with a laptop when im out. Sound isn't as good since I use an audio interface for my guitar to do the heavy lifting for my virtual amps that I don't have when I travel, but I digress.Basically, I have my Nux in the effect loop on my Katana (set up as Chain 3 in Tone studio, so its completely outside of pre and power amp). That way I can change settings on the amp all I want and the root loop or backing track I pre-loaded sound doesn't change with it. I run my wireless guitar pedal (the black one) into my multi pedal, and the multi pedal goes out to my audio interface (at home) or to the front of the amp if im elsewher. I have an 1/8 inch aux cable coming off the back of my audio interface and going into the Nux or the amp depending on what I want to do. This way I can play my guitar to wireless to multi pedal (if I need it), out to my audio interface or to the front of amp. The aux cable takes care of my virtual amps run by my computer. They play through it, into the Nux (if I want to be able to loop that sound) or into the back of the amp aux, out through the effect loop, and to speaker. This way I can loop with my virtual amps or not depending on my choosing by moving 1 cable (the aux).If I want to play just the amp, I just run the multi pedal out into the front of the amp-wireless guitar pedal is already hooked up to that anyway. Backing tracks already stored on the looper can be played out through the amp and I can change my amp settings for the guitar and play to the songs (remember, since im in the effect loop my amp changes don't change the backing tracks sound, just the guitar). If I want to actually loop, though, I do lose the ability to play my saved backing tracks at the same time unless I want them repeating in a loop unless I move the aux cable back to my amp. I can still play over them, I just can't loop (sound in = sound out with a looper). In that case I just either use the aux cable to play the backing track off my computer or the vitual amps into the back of the amp aux port instead using the Nux to do it.So, 2 cable changes and I can play either at home with virtual amps/pedals, regular amp and physical pedals, play backing tracks off the Nux for accompaniment, or my computer, or actually loop with the pedal if im so inclined.I'm writing a 5 star review specifically *because* this pedal is not simple to learn. I'm at about 80% mastery and even at this stage I can say I'd buy this pedal again.Here's the first thing to know: The NU>X loop core provides a bunch of features with a small set of control buttons; and the features (particularly drum tracks with level control) are great. BUT you will have to be your clever self at the party and bring your persistence as you learn the interface. There are YouTube videos and a passable instruction sheet; but you'll need to work with the device to get it down.My number one tip: Don't stop figuring it out until you can set up a rhythm track at your desired tempo AND enable automatic record-start. This plays the drum track (or metronome) without any worries about punching in on the stomp switch: Recording starts when you start playing.Number two tip: Making a recording does not Save the recording; so if you jump to another recording track your un-saved recording evaporates. Save is just tap tap on the save button and wait for it to write the track to its data drive.Another key is button holds (press and hold). This is how they fit multiple control features into single buttons, particularly the Save/Delete button and the Stop Modes button.No no no, lol. OK received and began to read or at least try to cypher the directions ah-ha. Then searched for help on you tube. I found 1 guy who managed to get through some of the functions and be able to direct you the viewer on how to use. Like him I was pulling my hair out trying to figure this thing out, but of all the features it says are available to ya good luck at achieving them. The description tells you all the things that can be done, but no directions on how to do it. SERIOUS as a heart attack! I've used several loopers no prb, drum machine piece of cake, but this thing lol... Ya know I've been in recording studios easier to use than this thing.Yes it sounds good ( the few drum beats I used), but again you would have to stick with that "phrase" if ya wanted to jam and loop with it. It's hard to explain because I don't fully understand the damn thing ( and I've been messing with pedals since the 70's ok). The reviews saying how great it is I just don't see it. Yes I created loops or phrase along with a drum pattern, but there is a whole nother dimension that this thing is supposed go to and I can't reach it lmao. I'm pretty good with equipment been building amps and messing with pedal insides for years, but I can not in good judgement tell anyone to buy this pedal. Especially if you're new to this stuff or just not that inclined. Ya know to be able to pick up pedals power them up and adjust and jam.It was a gift for my son who is self taught guitar player and loves all the options this unit gives him. Bought him a NUX mini amp earlier and was impressed with the build quality and soundGreat looper. I was skeptical, but since I'm not a professional, wasnt expecting much. I've had this pedal for about a year now, with no issues. It's made me a better guitar player. Love the tap tempo, and storage (6 hours). I can load outside source drum loops to pay along with, via a PC. The drum patterns it comes with are basic, but usable, and only after a year am I looking into a drum machine pedal to expand my choices. I've since purchased the delay and overdrive pedals from this company as well that I'm very happy with.I love a lot of things about this looper. It does what it’s supposed to do with one fatal problem- your loops will never be in time. The looper works by aligning your loops to a bar or bars of your chosen time signature. The problem is the metronome program they have is late by a very small amount. This will kill any joy you can get out of this pedal and it will actively make your timing worse. Do not buy.Tengo un par de semanas con el y hasta ahora no he exprimido todas sus funciones, pero desde el primer momento sabes que será una muy buena herramienta. Intuitivo en su uso. Las baterías no son las mejores en su sonido, pero son super útiles y cumple su función si son para ensayar o crear. Estoy contenta con la compraMuy buen pedal , lo buscaba por todas partes en mi ciudad pero nunca lo encontré hasta que lo ví aquí y me esperaba que fallara o así pero funciona perfectamente , trae secuencia de batería para acompañamiento y me sirve mucho para practicarSolo que el empaquetado venía medio mal y en la caja decía que incluye batería pero no venía incluída de ahí en fuera todo está muy bienWe use this mainly as a looper and I am satisfied. Wish there was a easy way of setting up beats per minute. Good product for the price. Delivery was fast.
