Are the champagne colored faceplates actual Pioneer productions or are they just nicotine stained silverface? I was surprised when I couldn't find anything on them via Google. Then on ebay I saw a "rare champagne faceplate SX-828" and to my knowledge, Pioneer never made such a thing. Does anyone know the real story? I'm beginning to wonder, because I just picked up an SG-300 off of Craiglist for $30 from some obvious smoker, and the faceplate seems to have a gold cast to it compared to my own that I've owned since new.
