Old-school Analog Chorus has always been warm but it was hungry for dynamic complexion. 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 develop an algorithm that mimics the principles of BBD chips - the key component of Analog Chorus effects. Rivulet's low-frequency activated provided the Traditional Analog Chorus Tone discerning ears have come to expect in a true analog chorus pedal. Dynamic Tone and Noise-Elimination ability put Rivulet into a completey separate category from cheap analog pedals. Quality-grade BBD chips in large mass have become incredibly rare, so this method is not 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.
