I've officially run out of things to say about D*A*M Tone Bender variations.  

The Black on Black has a larger coupling capacitor and a larger capacitor on the treble side of the tone pot, resulting in a lower cut-off on the high-pass filter.  It will have a far more meaty mid-range than a regular MKIII.
