Two ceramic capacitors from Murata Manufacturing, a leading Japanese company and the world's number one in market share. While 0.022μF (223) is the default for humbucker pickups like those in a Les Paul, it also works great with single-coil pickups like those in a Stratocaster, offering a different sound than the usual 0.047μF (473). I think ceramic capacitors suit single-coil pickups better than high-end orange drop capacitors. The color in the photos may differ, but they are the same capacitors.
