SG Identity help!

[johnny rg]

My singer recently came back from New York with a second hand SG guitar in tow, beautifully hand painted all over, we just can't identify the thing, it has all the appearances of a standard Epi/Gibson SG, except the controls, which I have never seen before as you can see it in the pics. Any help indentifying hust what on earth this is would be deadly
Thanks
John

Might of started out as a single pickup then had another added.

A bolt-on neck so it's not a Gibson. Controls could have been a single PUP to double conversion, or it's a knock-off so the controls are wherever the knock-off company wanted them.
