This BSR EQ-3000 10 Band Stereo Graphic Equalizer is a great addition to any vintage audio and video setup. The sleek design and excellent performance make it a desirable item for any audio enthusiast. The brand, BSR, is known for producing high-quality audio equipment and this item lives up to that reputation. With 10 bands of equalization, this stereo graphic equalizer allows for precise audio adjustments that enhance the listening experience. It is perfect for use with vintage electronics and consumer electronics alike. The equalizer sliders have been treated with Deoxit D5 and move freely and do not crackle and all bands work properly.  The graphic display worked while I was photographing the unit.  Later, while cleaning and testing the display was intermittent so I am not vouching for the display but the equalizer section is excellent.
