I'm a new forum member and this is my first post. My apologies, in advance, if this has been asked and answered. I've searched, but to no avail. I've just purchased a new McCarty 594 Artist Package. Most pictures I've seen show these guitars with "58/15 lt" engraved on the pickup covers. Mine, however, does not have this engraving. This is ok by me, but I'm wondering if anyone knows why some have this engraving and others do not. Thanks!
