Typed in “greddy Profec B Spec 2 instructions”
Then click on “i’m feeling lucky”
WOOT master google searcher.
But honestly i would just turn the gain and set all the way up, throw in some 89 pig piss and floor it.
Thanks alot man
It also on the greddy website as a .pdf file 
, and in english of course.
