Greco Rock Spirits Guitar

[Drumbob]

I just pulled the trigger and received a '92 Greco Rock Spirits guitar from Japan. It looks like a set neck and I was told by the seller that it is a set neck, but there's one large screw that runs through the body into the neck. I'm a bit confused. Does anyone know the story about this? I like the guitar a lot so far, but this screw thingie is confusing.

I once saw a posting about this on another forum.They are not set necks,they are screw on. There's 3 neck screws,the one that's visible on the back at the heel,and two others are hidden under the neck pickup in the cavity. They go through the neck tenon and into the body.

Edit - Here you go.I found the old thread.
