I've got one of the 6 string Grinds too, and I've played one of the newer Chinese made ones with a black finish. Love these basses! The newer ones are practically identical in playability, but have a much clearer and deeper sound if I remember rightly.
I've played practically every type of bass there is, from the most knackered Squier, up to vintage Fenders, Stingrays, Warwicks etc, and nothing has ever felt as 'right' as my three Peaveys. So they're the only basses I own! (i'm after a few more too!) Enjoy yours dude!
