The Dingotone "Black Stump" is very dark - a couple of us were calling it "none more black" pre production. That said, our resident mad alchemist Dingobass was responsible for Wudtone and now Dingotone, so an email to dingobass at Pitbullguitars dot com should be able to give you a full rundown on any differences. May also be worth looking at the Nullarbor ochre as well...
