This one cannot be used without modification. I have had to trim the top of the guard to clear the fingerboard. I've had to oversize the holes for the bridge mounting to allow it to line up. Sometimes it requires some clever repositioning of the guard to cover the old screw holes in the SG while you have to drill new holes for every mounting screw. Doesn't fit a Gibson, doesn't fit an Epiphone. What was this made to fit? Please redesign this one, Allparts! Lay it over a real Gibson pickguard and look at how different it is.
