In this YouTube video, Margrét Rósa plays a white Gibson Thunderbird style bass with a black one-piece bridge, black soap bar pickups, bolt-on neck, and white accent paint around the black headstock. [https://youtu.be/Pi_6ENKFKE0]
The headstock, however, appears to display an Epiphone badge rather than Gibson. Also, Gibson did not make the Thunderbird with a bolt-on neck. This close-up image of Margrét Rósa showing the headstock more clearly supports that it is indeed an Epiphone [https://images.squarespace-cdn.com/content/v1/57d79c7e725e250ead246879/1583583251886-V61AR6QKLES6KQI48XJH/Kaelan_Mikla_Gorilla_Manchester_March_5th_2020%C2%A9Johann_Wierzbicki%7CROCKFLESH-10.jpg]
Given this evidence, the bass appears to be an Epiphone Thunderbird Classic IV in alpine white. Sweetwater has a description and additional photos of this discontinued model on their website [https://www.sweetwater.com/store/detail/EBTCAWBH--epiphone-thunderbird-classic-iv-alpine-white]

I've seen Kaelan Mikla several times in Europe and New York, Margrét used a Epiphone Thunderbird every show, mostly the Goth version. Roadburn 2022 was the only time I've seen her use the Alpine colourway.
