Hails hurley, with no offense but, then you may have a bad mahogany, or a fake mahogany wood.. or either they said to you that itīs mahogany, but itīs not. it can happens.
are you sure itīs mahogany? any pics of the wood?
i had a Jackson JS-1 made in indonesia or malasya, and i liked very much the wood.
although it was deffective i guess. i swaped several(5) pickups in the bridge and it continuously giving me one Middy/bass sound.
although i could perceive the tonal/vibrations nuances of all 5 pickups , the sound that was being spitted through the speakers, are the same.
so i traded the guitar. ahahahahah
