I remember chrisguitars, usually a decent site, had a Coronado II bass listed for quite a while. For some reason, an owner had crudely gouged a hole, roughly the size of a cornflake, into the back of the neck around the 5th fret and inlaid a plastic jewel, like an emerald. They probably used their cro-magnon forehead to hammer it in. It was't a clean job, it wasn't a smooth job, the jewel stuck out, quite literally, of the neck. Eventually, it sold too. People forgive all kinds of sins if the thing is old.
