Amazing for audio shaping, whether boosting or cutting.Very good to excellent condition. Fits 500 series rack.This is a limited offering. I have two units left, (both have Purple Audio OpAmps) once they are gone….they're gone. Equipment such as this is a good investment; the value just seems to keep going up. This EQ is Absolutely functional and all bands are working flawlessly. Includes original electrolytic capacitors.The incandescent panel lamp has burned out, but that is normal, and can be replaced with a led. knobs have been repainted but I can supply you with old-stock knobs if you prefer.I got this eq from a radio station in North Adams Massachusetts and have used it in my studio on many recordings.
