Mike Tobias often uses wenge necks and fingerboards for his MTD basses. To my ears, wenge produces a tonality that is quite distinctive and tends to dominate the tones produced by the other woods used in the neck, or even the body, of a given bass. Subjectively, wenge is a little dark and very punchy (meaning that either the attack or the decay of the note, or both, is quick). I tend to think of bass tones on a continuum, with a tuba being at one end (dark and punchy) and the bass notes of a piano on the other (bright with lots of sustain). Wenge produces tones that are more tuba-like. Does that make sense? To my ears, ebony produces a tone that is dark, but with lots of sustain. A piano without the upper harmonics, if you will. Wenge, though dark, attacks or decays much faster, and so it doesn't sustain nearly as well. YMMV, of course.
