It could be pixies. I sometimes leave the window open.
At some point during its period of rest I remember I mucked about with the pickup heights. I've tried that several times before and it didn't help, but maybe this time I found that magic spot. So that's another bass where I can't adjust or change anything, including the strings, in case it all goes to ratshit again. Fortunately string height and intonation doesn't bother me that much.

Measure everything, now, while it sounds great. (Take photos ) Then you might have a chance at getting that sound back, later.
