Vivie CORAL CHOIR I think it's a very excellent chorus pedal. I haven't stepped on it directly because it was connected to a switcher. It's in perfect working order with little use. Original box and instruction manual are included. Production has ended, and it's difficult to find used ones. The brand's first chorus pedal, which achieves a wide variety of sound creation, has arrived. Vivie, a rising domestic pedal brand that has been attracting attention in recent years and continues to gain support from bassists and guitarists, has released its first chorus pedal, "CORAL CHOIR." This unit is equipped with knobs such as "RATE" to adjust the speed of the modulation, "DEPTH" to adjust the depth of the effect, and "MIX" to adjust the balance between the original sound and the effect sound, which are included in many common chorus pedals. However, the most distinctive feature is "DIMENSION." This knob can continuously control both single-phase and multi-phase chorus, and by adjusting it in combination with the MIX knob, it enables a wide range of innovative sound making unique to this unit. In addition, although this unit is an analog chorus, it features a buffered bypass specification that employs a digital switching method to eliminate switching noise, in addition to high-quality bypass sound, thus preventing the sound quality degradation inherent in analog circuits. The vibrant casing design is inspired by sea coral, matching the company's popular delay/reverb pedal "DolphinDeverb," and the gradation coloring and other details reflect the company's unique look, with even more attention to detail than before.
