The Sonic Gray Jazz comes stock with a Parchment pg. One of my local shops just got a few in, and the Sonic Grey is definitely parchment, while the Oly White P, Sunburst P and Sunburst J basses have thr mint pg. I'd post a pic, but I'm not there now. I personally think that the Sonic Gray would look better with the mint pg, but it's a personal preference (I'm not usually a fan of white/parchment pg's).The American Professional basses have 3-ply Mint guards, not white.
