NUX NCH-2 RivuletRivulet ChorusA 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. 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: MODERN CHORUSThe 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. 70?s CHORUSThe 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. 80?s CHORUSThe 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 ratio adjustment.Features: 1. Free Firmware updates. 2. True-bypass or buffered-bypass selectable. 3.
