I recorded this about 3 weeks ago. Sorry for the bad video. I missed windup and most of wind-down(I couldn't find the clip that had the end of the wind-down). This modulator is really sick. It was quiet and the drivers kept popping. I'd like to note this modulator is on one of the older MC/MCP controller's.
