My Indonesian sterling (SUBrays) certainly does not use maple for the body, more like something very soft, light and porous (I bought one with a big chip out of it from MF). Seriously reminds me of the balsa wood i used to make toy planes from. Advertised as 'solid wood', 'extremely light and airy". I can't imagine why they would ship such stuff from the States.
great bass for the dough by the way. Neck and fretwork is excellent.
The subs have some kind of basswood for the body. They have something with a grain pattern similar to maple for the neck. Because of the tint, it is tough to say what it really is.
