This Rupert Neve Master Buss Processor is intuitive to use and sounds incredible. By the time you have set the stereo compressor, limiter, silk, and stereo field eq, the source can be completely transformed. At the same time, it can do this in a very transparent way, making it incredibly versatile.It is is mint condition, just as it arrived. As shown in the photo, the channel B limit knob arrived with a tiny black mark on it, but this is barely visible. I didn t notice it in practice, and it could be easily remedied as the knobs slid right off by design.
