Well the SYOD had its origins as the DAOD prototype that Bjorn built for me in July of 2006. It was designed to be a companion/stacking buddy for the DRD, as that's what I was using for distortion.
If you do a search, you can get more info about how it works and sounds.
But yes, the SYOD will play nicely with the DRD, as that is what it was designed to do in the first place.
Have fun
Doc
