There is one other full band Blues Brothers custom that has been made. Maybe the author will one day be ready to pull the trigger and put it out there.
To whomever owns this BB custom...please consider sharing it at some point. "As-is" or "not up to C3 quality" isn't ever damning indictment for most of the community here; we're a pretty understanding bunch. We'd just love to be able to play and appreciate the awesome songs that you've spent time working on. Perhaps the community can even help fix up whatever you'd like to have fixed up. My mama always said "You don't G-E-T unless you A-S-K".
You can even consider it a "mission from God", if you like.
