Just sounds like a delay with a wah with a clean guitar sound. The 'scratchy' sound comes from raking/scraping the muted strings.

There's some other guitar work in there, but it sounds like the same effects going on

EDIT: Based on the other little guitar licks, I'd guess there's a compressor in there too.

muted alternate picking on the upper end of the neck using probably first second or third strings. probably a wah too or it's just high pass filter
