Nux mini core Rivulet effect pedal- CH2.A crystal clear river  flowing, transparent.  The  Rivulet design concept ! Old-school Analog Chorus has always been warm but it was hungry for dynamic completion.  
NUX’s modern-tech DSP yields a perfect combination of both worlds: analog and digital.
To achieve all of the Rivulet Chorus objectives, our engineers had to developed an algorithm that mimics the principle of BBD chips--the key component of Analog Chorus effect.
 Rivulet’s low-frequency oscillation provides the traditional analog chorus tone discerning ears have come to expect in a true chorus pedal.  
Dynamic tone and noise elimination capabilities put Rivulet into a completely separate category from cheap analog pedals.
Quality-grade BBD chips in large quantity have become incredibly rare, so this method isn’t practical for making an affordable analog chorus device. 
Using DSP technology, NUX is able to offer a mini-pedal with a contrasting array of chorus tones.
