Versatile and rich with features.
I am a working, gigging acoustic and electric player I tried several pedals for my D-35 and Takamine TAN-15C, some worked on one but not well on the other. I also didn't want to hand over tons of cash for something I'd be stomping on. The Nu-x proved to be tough and is built to last with heavy duty switches and knobs.
It's easy to dial in tones for very different sounding guitars using the Bass, Mid and Treble controls. They have a broad sweep to cut or boost their respective ranges. The scoop feature is pretty useful to dial out excessive midrange, and the notch is very good to knock out feedback, together with the frequency select control. Go easy on the treble when the scoop button is ON!!
I use a small amount of Reverb, which is pretty good on the pedal, just the right "Size", somewhere between Big Room and Hall, which can be nicely dialed in but has enough to make it really wet if needed.
The chorus is a bit subtle but not too whooshy or fizzy. I use chorus sparingly so it's fine for my needs, which range from flatpicking to strumming, to fingerpicking.
Lowest on the list is the looper function. I don't use it. It's a bit weird to use and while it works fine, requires you to be a good dancer to hit the switches correctly. In spite of this, I still give the pedal 4 stars for features because it sounds much better than other, more expensive pedals.
Other features like the XLR output gives multiple connection options, useful when your mixer has run out of Jack inputs. Ground lift, USB and other connections, I have not even tried, so I don't know what they can or can't do.
You'll not find another pedal this competitive at this price point!
