Does anyone know where I can find a model number for a specific Pioneer 2-channel home stereo equalizer? I don't remember much about it, except that it was black, had controls in the middle of it I believe for each frequency which was represented by a blue/red display that lit up with it as well, which went horizontal cross the unit, presumably one side per channel, sort of in the shape of triangles if I recall correctly. Probably made in...I don't know...mid-late 80's? Maybe 90's? I'm not certain. I've scoured eBay and Pioneer's websites, Google... I know I'm being extremely vague, but I'd appreciate any help I can get, thanks!
