This Sansui SE-2000 equalizer is in excellent condition and fully functional, including all leds on each of the sliders. All buttons and sliders work very smoothly and the unit has an overall ‘like new’ feel. The black casing is in remarkable shape and shows only a few light marks on one of the sidepanels near the back of the unit, as can be seen photo 6. Otherwise, it looks fantastic.
