Kinda random, but I found this vid with bassist Janek
Gwizdala showing a Fender Musicmaster bass formerly belonging to Jim possibly during his SY era. Relevant to gearography maybe? See ~4:50 min

Edit: I thought he was showing Jim’s bass, turns out the one he shows is very similar but not actually Jim’s. He played Jim’s in a studio, loved it and bought something similar
