Did you turn up the gain mini-pots for the pickups before this ?I have tried bypassing the preamp and taking the signal directly from the pickups (also bypassing all potentiometers) and still low output.

Now when you mention this, my bass have a replaced preamp(replaced by former owner), the one I have is a Noll preamp that is unity gain. Can it be that the Tune pickups are low output that relies on a boosting preamp?Did you turn up the gain mini-pots for the pickups before this ?
That's not how I remember them.Can it be that the Tune pickups are low output
I have adjusted the pickup height and while it did increase the output its still much lower than my other basses. The pickups in my bass only have two wires plus shield and it looks like it is wired correctly(ground+shield and hot to output).That's not how I remember them.
Has the previous owner set the pickups too low ? Have they wired the pickups parallel, Green/White to output Black/Red/Bare to ground, ?
Yes, i'm grateful for the help from you guys. I love my Tune, it sound great, just very quietNot with my TWB4. My PuP’s always seemed at least as hot as others.
Maybe someone else here will have an easy fix, and/or some idea of what to look for. You’ve already done more than I would know to do.
Happy to send pics of my internals, or anything else that might assist you here.
Edit - when I started my reply there were no other replies, lol. Glad to see the community is here to help.
Your bass came with SWS-4V pickups for both bridge and neck. Those are 4 coil humbuckers, could be they have been joined under heat shrink with a single hook wire added then run to the preamp. Could just be for clarity but that's how it's shown in the attached PDFs.The pickups in my bass only have two wires plus shield and it looks like it is wired correctly(ground+shield and hot to output).
Wow, 4 batteries? My Bass Maniac only had one. And when the circuit board went bad, I replaced the pickups and preamp with a set of passive pickups from Epic Custom. They sound good and have pretty strong output for passives.Here's a pic from my archive - not sure if you can see what you need to see here. Let me know if this helps, or if you need something more detailed and I'll get different angles. Probably about time to change the batteries anyway

My pickups only have two wires, there is no heatshrink. Maybe Tune used different pickups during different production periods? Mine has serial number 107057, past owner thought it was from the early 90s.Your bass came with SWS-4V pickups for both bridge and neck.

Beautiful bass! Used to be that QParts sold replacement knobs.View attachment 7066827
Just joined the club. 2017 Korean made. Anybody know where I can get the replacement caps for the control knobs?
Had a friend at work 3D print some. They’re pretty spot on.View attachment 7066827
