NUX NCH-2 Rivulet
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
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. We selected 3 essentials, each with a voice
that can be upgraded with a quick, user-friendly firmware download.
Here are NUX’s 3 essential picks:
The Rivulet comes factory-loaded with NUX’s tribute to the classic “Modern Chorus,”
the familiar Yellow pedal with 5 knobs. The original pedal required a whopping 18 volt power
supply to improve sound clarity and boost dynamics. The Rivulet out-performs this respected
beast w/ a mere 9 volts. We’ve also consolidated the controls by eliminating the bass and
treble knobs, now internally set at middle position, and we’ve eliminated the need for
the bass filter altogether, which is now automatically corrected through the advancements
of DSP sound modeling.
The first chorus effect pedal arrived on the scene in 1976. Before that, it was only
available as a built-in effect on a classic jazz amplifier. Rivulet accurately brings
back the characteristic of this pedal; that special warmth of a rich jazz atmosphere,
that immediately recognizable highlight to any musician’s tone.
The classic original only came w/ Speed and Depth control parameters, just 2 small
knobs, and yet it was recognized as one of the best chorus effects of the 1980‘s.
Rivulet’s 3 knob configuration provides the added benefit of a dry/wet signal
