From the Suhr site: Mahogany A popular wood used in set-neck guitars and acoustics, Mahogany is strong in the mid-mids with a good high-midrange bark. Contrary to popular belief, Mahogany is not dark just strong in the mids that gives it the aural illusion that it's compressed. Mahogany body is best when mated with Mahogany neck. Mahogany Back / Quilt or Flame Maple Top This is another killer combination when mated with a Mahogany neck with various species of Rosewood for fingerboard material. Maple extends the range of Mahogany with more brilliance and punchy lows. The Mahogany back and neck combination works well in the bolt-on design and is highly recommended for those seeking a thick woody tone. My question about this is, with an all mahogany body, will notes played in the upper registers (top E and B strings up past the 15th fret for example) be lacking in volume when compared to a mahogany body with maple top, all other things being equal? Or will it just be a different tone, with the same volume?
