The ESP Guitar Company

It depends on where on the fingerboard the buzz is coming from, but I've found that checking the relief solves as many buzz related issues as raising the bridge. There still may be an issue that needs to be corrected by a fret leveling, but it's worth checking everything else out, first.

Not meaning to spam, I recently put together a video about how I setup a guitar for myself. It takes a reasonably detailed look on how to do that type of work, yourself. Maybe it will help you out.
