The song is on Youtube over here:

The guitar solo starts at 6:24 and ends at 6:32. It's really short, but I'm wondering how I could make up my own solo to fill in for here instead. My friend told me I have to use scales, but I can't figure out which one to use. Could anyone tell me what scales to use for this solo?
