UsedBuy It NowBest Offer

Motorola EQB 4001 Graphic Equalizer Booster 1980s vintage tested with bracket

Had this for years in my Torino hooked up to an aftermarket stereo. Set the controls and switched on, mounted behind the dash so that it was always on with the key. This may have spared the face of more wear over the years. Powers up and works fine. Took the top off to blow out and visually examine while I also bent the top louvers back while I was at it.
