Based on their other videos and builds, I don't have much doubt that they could make one of the very best fake Super Eagles anyone has seen. Still not up to PRS standard but as far as fakes go, extremely good. However, I don't think that's what they are trying to do. They are making unique design changes.
Of course, they are definitely copying the super eagle. That's an ethical dilemma on its own but guitar manufacturers have been copying each other since guitars were invented.
I don't want to be misunderstood. This video rubs me the wrong way as well and if I had my choice, I'd rather they didn't go through with it. It's just they seem to have pure intentions.
