Operation confirmed. This is the signature model of Daniele Gottardo, an Italian technical guitarist. It produces distortion to overdrive sounds using germanium transistors. Although it uses germanium transistors, it doesn't have a fuzz-like quality at all, and I think it's an easy-to-use effector, along with the equalizer. I think the sound has a quick attack and good note separation. The on/off confirmation LED has been changed from blue to white (from the time of purchase). "SPECIAL GERMANIUM TAPPING DISTORTION"
