For their necks? I know hard/rock/sugar maple all reference the same species of tree, which is the tree you get maple syrup from. In adverts, I mostly just see "maple neck", not specifically stating hard and/or rock. Anyone know what they use, and if they changed it, when? I've seen other brands use terms like "eastern maple" or "big leaf maple" when referencing caps/tops, which I'm guessing is softer because it's not being used for necks, but I don't know.
