MEC mid-control does nothing/not working, output seemingly unaffected

[Extra]

Hi guys - quick question for those more than I in the elevtronics dept. I recently bought a Streamer Stage II that sounds phenomenal, but the mid-control does absolutely nothing. No cut, no boost... turning the knob has zero affect on the sound. The pot itself is a 100K pot (diagram here: https://www.warwickbass.com/media/man...024 rev2.pdf) and as best I can tell everything is installed and wired correctly.

If the pot went bad or just wasn't wired in, wouldn't it affect the tone somehow? I do find it interesting that the output is the lowest of any Warwick bass I've ever owned, so perhaps that is related. Any thoughts or suggestions will be greatly appreciated Thanks!

That sounds like a problem with the pot: I have heard of pots failing in such a way that turning the knob makes no difference. It might be something else, but I'd fit a replacement pot - it shouldn't be expensive even for a center-detente pot - and it'll easy to fit. So if that doesn't work, then you haven't lost much. But hopefully (and probably) you will find that it does work!

On my former Jazzman, the treble Pot was wired and working, still, it had almost no effect at all on the tone. Seems like the preamp was pretty weak in my case... just my 2 euros cents.

Yessir, you are correct. So, funny story...

After using my Streamer today as a pure recording signal, I decided to give the knob a twirl. Lo and behold, it works just fine - it's just friggin' near imperceptible Now that I've picked up on it I can hear it, but overall the tonal range of this MEC pre is WAY less than the range of the 2-band MEC pres in my old Corvettes. Perhaps a battery change is in order.
