Somewhere in late 70s or early 80s, I had a Fender J on which I installed black tapes. The tone was fine enough to keep them on for a couple years, but they were nothing special really. I had no problem with rattling though.
To be clear though, I mainly put them on for the feel and looks. They felt great to play and the visuals (I could see then) were cool. Black strings running down a maple board with black dots across the white guard of a tuxedo with chrome covers & tray. Even if nobody else felt the same, I thought it was a happenin' machine.
