No, just remove the chrome cover from your OV's neck pup,
it'll be like taking a blanket off of a speaker. Just my opinion.
I have a set of Rio Grande pups, no cover on the neck pup.
A set of OV's with the cover still on (being removed as we speak
by Avenue Guitars) the Rio's sound more "open" to me.
Just be careful if you do, there's a wire attached from the pup
to the cover. Every guitar and pup combo sounds different, just
whatever "flavour" you like.
