On my Xiphos, on the 12 and 13 frets on the high E, I have recently lost most sustain and when i play them, there is a quick kind of vibrato sound. I went to Long & McQuade and they said it needs a set-up but I need this guitar ready for Monday.

What is wrong with it? The action? What?

And how can I fix it?

what's pron?

EDIT: i googled it, you guys are gross.

for a temporary fix, just raise the action just a bit on that side of the bridge, but once you get the chance get a set-up.
