Much of Texas Flood used a Dumble, but I can't comment on which songs (I'm no SRV fan).
Texas Flood has some of the greatest tones ever laid down on an album and a lot of it was a Dumble - but not an ODS, it was Jackson Browne's 300 watt bass amp.
There is an interview with Howard Dumble somewher on the net with the details. SRV had his own Dumbles later, but they were Steel String Singers which (I think) are single channel clean amps.
I don't have mine yet, but I reckon the overtone will be versitile enough to give a decent edgy, stratty SRV type sound (at least I hope so).
