I used water with a little bit of washing up liquid, then did it again with just water. I am thinking of having a container of isopropyl alcohol around to soak strings in though!
Did a big trade with Russ and then ended up doing another transaction with him a few days later. Serious collection and wow the guy can tap! Will stay in touch.
So technically still the factory of manufacture, but for the case rather than the bass 😊
Lovely instrument btw. I popped it in the 32” scale thread too.
