GC generally gives you 40% of what they think they can sell it for.
PRS SAS or Gibson LP Standard+
Teese WOF->Analogman Sunlion->Dr. Scientist Elements->Foxrox Aquavibe->Strymon Timeline->Eventide Space
Mesa RoadKing II and 2 Vox AC15s run in stereo
If it's in perfect condition, they'll probably give you ~$150-$200. If it's beat to sh!t they probably won't take it.

Instead of wondering, why not just call them and ask? They should be able to tell you a rough estimate over the phone...
