This is a cool custom made double neck SG style guitar / bass.  
The body appears to be quite old, probably 70's.
Both necks are Epiphone.  The guitar half is all epiphone parts, the bridge, pickups, etc. 

The bass pickups and bridge are off of a 70's lawsuit SG bass.  

Its been tested and is working.  The bass sound has very cool vintage tone, just what you would expect from a 70's sg style bass, and the guitar is basically an epiphone with a 70s body.  It plays good and the necks are straight, however you will probably want to set it up according to your preferences since this guitar hasnt been in regular use, but the action is completely adjustable.  A couple of the volume pots did display a bit a crackling which could be cleaned, or may go away with regular use.   

This is a totally unique one of a kind instrument!

(The auction was removed, because i used the word gibson to descibe it in the title.  I'm sorry to any previous bidders.  I've changed it and hopefully there will be no issue this time)
