83 Gibson Les Paul Studo... Custom?, Need help with identifying guitar Options

[kristingish]

Hi,

I have an 83 Gibson guitar. I don't know very much about guitars at all, but it does say studio on it and the serial verifies that it's an 83. It looks like all of the other 83 Gibson Les Paul Studios with a few exceptions that I don't really understand

On the back of the base of the guitar, all of the others have two plates: one diamond shaped one on the bottom left and one small circular one on the top right. Mine only has one bottom left diamond shaped one and no circular one on the top right.

Also, usually there is a switch on the top left of the front of the base, but mine has the switch next to the knobs on the bottom right.

I know that I sound really retarded, but I know nothing about guitars.. so I have no idea what this means. I'm trying to sell it and I can't because I don't know what to say about it.

PLEASE HELP ME!

<3 kristin
