I'm considering trading for this guitar, and I'm hoping that someone(s) out there might be able to help me determine its ballpark value.

The serial number is 91017252, though as I understand it, this is not necessarily useful info for determining what year/location of manufacture it is. EVH's signature and a patent number are stamped in black underneath the serial number on the back of the head stock.

As you can see from the pics, the guitar has a single knob for volume and is a cream/off-white color.

Any help would be greatly appreciated -- thanks!
Ebay completed listings have it between 500 and 650 for a run of the mill Special w/ hardcase. GLWS
