Three basses Go South in six different amps with no bad cables, and the rest of your basses are fine.

Are there crop circles in your back yard?

worried that something in my house is causing the problem
MM and spector there's no semi-local shops certified for them, the brubaker was modded(not by me) with a duncan pre in it. brubaker a friend and I just spoke and he thinks bad solder joint. The other 2 are factory stock with no mods, but little to no output.“Dying” so there’s no signal output at all on those 3 of your 26 basses?
You really haven’t detailed what the actual symptoms they’re experiencing are.
The smart thing would be to just make appointments at OEM certified techs for each of the three basses and to also immediately open dialog with MM, Spector, and Bru directly regarding detailed specifics of their products’ failures.
I have two older Carvin active basses (1992 and 1993). Each has seen MANY hours of playing. I started noticing the same thing. I didn't see it in this thread but I started having similar issues with fresh batteries, etc. I even pull the batteries when not in use. For 4-hour gigs, I would hear some distortion coming in. I tried swapping batteries, chords, amps, speakers. I also sanded the battery tray contacts and few other desperate moves. It just seemed battery life was decreasing even with the same lot of 9V.
In my case, because I had 30+ years of pulling batteries and putting them back in, I started wearing out the wires connecting to the battery tray. When I went in to re-solder the battery tray contacts, I saw that the tray wasn't holding the contacts tight against the battery. I bent the contacts for a better connection which improved a bit but that wasn't good enough. I found the same/knock-off battery tray on Amazon. I bought one to try on the guitar I use less and VOILA! It's been perfect for >2 years. Batteries act like they last longer due to better connection. I switched-out the other one ~3 months later.
I didn't see if you had a lot of miles on your basses.
About 1/2 my basses I bought because they were collectable or limited editions, and most of those are passive. But whats confusing me is the MM, because it has low playing time on it, so hardly any wear. I have a Spector from 98, and a fender from 94, no issues with either of those basses and they have been played quite a bit.I have two older Carvin active basses (1992 and 1993).

I'm going to check that on the Spector and the MM next. Didn't even think of that at all, and none of my musical friends suggested it either, all I checked was nothing was frayed or loose. Thank You!!You may have measured the voltage at the batteries, but did you measure the voltage at the preamp power in, where the wires are soldered, (with an instrument cable plugged in so as to close the contacts on the output jack)?
As much as I enjoy active basses, the plug-on caps or the single or double battery boxes could stand to be far sturdier than they are, especially their wiring pigtails.
Blew my mind when the Spector was diagnosed as easy as it was, thing that's a killer on that is it's a 2017 bass. The one that has me nervous is the Musicman, have a feeling that one is not going to be as easy of a fix.That will be wild if all three basses all started croaking at the same time with different causes.
Yes I do, that's what I'll use on the Brubaker to make sure it's the battery box.Do you have a multi-meter?
Yes it came and went as he messed with the pot, so this one doesn't scare me now.I hope in regards to the Spector that it is just a pot. When the tech did what you described above, I am hoping it was a repeatable issue with messing with the pot?
