I find poplar to be very out-front with the mids, and would rather have an ebony board if it was maple/poplar.
My only rosewood time has been fretboards. Only 3 of my guitars have rosewood and the rest have ebony, mostly because I prefer the look tbh.
For the type of pickups I like best (high-output ceramics), rosewood lends the extra warmth that's easier to work with IMO, while still having the bite.
Ebony is definitely crisper but not as warm (on average).
Small differences in the big picture, but enough to change the boost or amp knobs just a hair.
A smoking hot thick A5-based model like a tone zone would probably go in a maple/alder/ebony guitar for me. (which I don't have sadly)
I've considered sometime getting the ltd black metal M-series floyd model,(maple/alder/ebony) with the single custom Black Winter.
Probably would be tempted to snag the BW for another guitar and use the ltd for a tone zone. I really want a blackened BW!!!
