Good topic. The traditional tropical hardwoods are great, but I've become more interested in domestic alternatives.
Of the traditional woodworking varieties, Cherry is one I'm not tired of yet. And Sycamore is an unscratched itch for me. A hardwood I like that I never see used for guitars/basses is Butternut, which I think would be great for bodies. And then Douglas Fir... always watching for that. I've got some old pieces I'm hanging onto for when I get a real shop again.
I've been making small craft items from Mesquite for a while, and am always interested when it's mentioned for luthiery. Bonus if the usual bbq jokes are skipped. I have some scrap pieces of Mesquite flooring that were sourced from Texas, and some firewood logs from Arizona. Both are on the dark end of what I see online. The wood is hard but workable, strong, and stable. In fact, the flooring I rescued from a scrap pile that had been left outside for several years. It was still straight and in good condition. It can darken significantly with heat, and also goes almost black with iron acetate. Closed grain, similar to Pau Ferro. It would make a good fingerboard, and would also be good for a neck, if you can find a big enough piece. Heavy, yes, but I see people making necks from other heavy materials, like Rosewood and Wenge.
Decades ago, I turned a broken Thunderbird bass into a neck-through with laminated Hickory; chosen for it's high MOE. Not nice to work with, and tended to warp. Based on that limited experience, I'd leery of Pecan, but I haven't worked with it.
A few other oddball woods domestic woods I've used and like:
Arizona Cypress - the pieces I've had were lighter than Sitka Spruce, with straight grain. Not a commercial species, but they get large enough for boards.
Manzanita - very hard, and strong, but big pieces are rare. Loved seeing it used in the Tubscrod project.
Ironwood (Hophornbeam) - another potential candidate for fingerboards, I'd think.
Alligator Juniper - nice color and grain; dense and hard for a "softwood". Smells good too.
