The ASDC is GNI's ultimate Analog Chorus solution. With this pedal you can achieve the full intensity that only true analog (BBD) circuits can offer. It's use is very similar to DD1 (Dual Drive), with the difference that upper and lower units have the same effect. So, you create two independent settings and switch between them. You can instantly change from a very fast rate (almost a "Tremolo") to a slow, deep effect, with no interruption in your performance.
