I have a late 90's or early 00's Parker Nitelfy, and I would like to have the top hand completely painted (including the pickgaurd). Is this going to dramatically affect the sound? I spoke to the local guitar guru, and he told me that if it was an older guitar with a specific type of lacquer finish (I think it was some type of polyester coating, but I could be wrong), it would noticeably affect the sound. However, since most newer guitars do not use this type of clearcoat finish, I was told that hand painting would minimally affect the overall tone of the guitar as long as I clearcoated the finish when it completely dried out. What do you guys think?
