Use the allen head or standard-slot screws on the sides of the rear bridge....One on each side........Bring the entire action up or down to suit your tastes....If you get it down nice and low and only one or two strings buzz, than use the tiny allens on the individual string saddle itself to raise it....MAKE sure ya don't have the buzz comin from the top bridge slot that may be cut too deep.....This could be a headache getting it right.....No offense, bro, but use common sense.....V
