If I wanted a Cobain Jaguar for collecting purposes, cause lets face it, I would never play it live.LOL
I would just save and get a vintage one with dots and binding then route it out and install the humbuckers, and then add the extra pot/knobs and change the hex plate.
That's as close as you'll get and as authentic as you'l get IMO.
The CIJ ones are wrong, they're close but still wrong. For a start his TOM wasnt angled like that, it was angled slightly but it was drilled straight. It was angled with tape adjustments.
The pickguard is the wrong color too.
