I get a bit of buzz, but it's because i have the action set low. I COULD take in to a repair shop and have it set up properly so there's no buzz but I don't care enough.
The buzz is barely (if at all) noticeable through the amp, and what little imperfection that exists just adds to the feel.
In a nutshell, if it bothers you fix it. If it doesn't, don't.
