Haruna's EVH 5150 III amp isn't visible in photos from several of the Luminous tour dates, and during the Zepp Haneda show broadcast, it is on stage but not plugged in or turned on at all. The Shinos amp is still always there and plugged in—though with no mic in front of it, it's hard to tell if it's actually being used or just essentially a prop—but the EVH definitely is not being used. There's literally nothing plugged into the input, and the power light is off.
Maybe she stopped actually using it before now and I just didn't notice, but it's at least looked plugged in as recently as the 15th anniversary show. In any case, for the Luminous tour, it seems it is no longer actually part of her sound.
(I do suspect, since there's no mic on the Shinos, that she's plugged into the Shinos amp but plugged that into the EVH cabinet, firing backwards and mic'd behind the stage. This would make life a lot easier for the venue technicians to get a clear sound. She probably then has the EVH head still on top of the cabinet because that's how the flight case is designed, and it can serve as a backup. But that's all speculation.)
Also, recently I finally got many of the band score books, and in the band score of Temptation Box, it specifies that Haruna uses Ernie Ball 9-42 strings, not the 10-46 which the first post specifies (and Mami uses). Of course, it's possible Haruna has changed string gauge since then, but the other books don't mention strings at all. So I don't know if there is a more recent source which confirms she moved to 10-46, but the book confirms she had 9-42 at least up until late-2010.
