There’s a misconception that every fret neck buzz manifests through the amp- bogus. If you are experiencing a neck buzz, crank up your amp & listen well. If you hear buzzing, then there’s a cause for concern, most of the time there won’t be any. Your pickups job is to pick up the vibrations at the picking end & not the fretting end, that’s why fret buzz isn’t amplified.Amplified buzzing suspects are (most of the time), cable (lead to some of us…)/ speaker (cracked cones)/ pedals…

Paul Gilbert’s philosphy is this: go as low as you can, even if it buzzes, as long as it doesn’t get amplified, if low action helps you play better. Otherwise, stick to the default action.
