Having owned a couple of MTD's and played a lot more, the one wood option that makes a massive difference is a wenge neck. That is the 'original, classic MTD' sort of spec, with an ash or other lightweight body. That will give you the maximum 'scoopy sizzly' Norm Stockton sort of tone... very upper treble, sweet sizzle, relaxed mids, and then a huge, open low end.
That is kind of the 'outlier' for me on MTD basses. The other wood combinations (i.e., ash neck or maple neck, maple board, rosewood board, mahogany body, alder body, etc.) are more 'tweaks' to my ear on a more relaxed, mid present, less sizzly MTD tone.
I LOVE the ash neck, maple board, ash body with a top of your choosing (walnut looks amazing) spec. Plenty of snap, but some real growl and punch also. I had this spec with a Koa top for a while... very big and punchy, and a little less 'extremely modern' as the Wenge/ash spec.
IMO!
