No problem. I listened to that overdrive a lot - I have dozens of recordings of her playing in the band, and can pretty much call it up from memory.
She did not go for the bright fuzz sound at all, so I suspect it would have sounded a lot different if she'd kept the high end flat on her Magnum IV. She took all the highs out, then cranked the treble down on her Ampeg as well; combined with the DOD, it gave a very powerful, deep but surprisingly distinct sound out of the amp (don't remember the model). It meshed well with the guitarist's very bright Telecaster tone.
