Hey tany, you should do some research before you post.
You got quite a number of points wrong.
Mahogany has a pronouced lower midrange plus the tone is usually richer. Basswood is more or less a neutral wood.
The Tonezone is uber bass heavy, and super high on lower mids.
Lower mids give you CHUNK, FATNESS. You get the idea.
For the SZ, its generally dark sounding. The Air Norton (AN) and Tonezone (TZ) are dark sounding pups. There WILL be a chance your tone gets muddy, its your personal opinion. On the other hand, you might love the dark, smooth tones both pups give. With heavy distortion, you got thick and dark crushing chugga.
I have a recommendation. A Breed neck in your bridge. If you check out the Dimarzio website, the Breed neck seems to ROCK in a set neck mahogany fixed bridge guitar.
I am using a Breed neck in an S series.
For the neck, AN might mud out on the lower bass notes. Consider a PAF Joe (think smooth but a tad hollowish sounding, I have clips of it) or a PAF Pro.
