Update for those interested: Communications are slow going with the owner but mainly because he's been busy promoting his band's new album. He contacted me with an update yesterday saying he'll soon have time to deal with the bass. I'm in no rush. I've been following them and am really enjoying it. It's gotten me interested in Korean culture, too. Ugh, be it not for COVID I'd go to Korea and time it to see one of their performances and bring my bass back with me.
Cheers, all!
