Tube Screamer TS10 hums - even when off [PROBLEM SOLVED]

[BassOliverB]

Hi guys,
So, I know this is in some ways guitar related - because it's a Tube Screamer guitar pedal, but heck, the science behind it is the same...!

So, I'm having trouble with an old Tube Screamer TS10 pedal that I got secondhand... It seems like when it is in the signal chain, it "boosts" the almost non-existing single coil hum coming from my stratocaster, but it goes away when i turn the volume on my guitar off... It's kinda annoying, and I am wondering if I can get rid of it?

Any of you experienced people know what to do or look for?

The power source is a Voodoo Lab Pedal Power 2 Plus.

Thanks

Have you tried it without the PP2 and used a battery or other regulated 9V DC power supply? Sometimes the PP2 doesn't like certain pedals.

I can try that... It would be kinda unfortunate if it doesn't like the power from my Voodoo lab

You were right! It needs a battery. But you know what the funny thing is? The battery alone as power source works perfect - the Voodoo Lab alone doesn't work well, but having both plugged in works perfectly! Even though the power adapter makes the battery inactive...! I think I'll just leave the battery in there and plug the Voodoo Lab back in ;-)

It even sounds nicer now...!!

You have either a cable issue, bad solder connection on the jack grounds, dirty ground contacts in the jacks or power supply issues. Putting a battery in the TS10 shouldn't make the power supply work better.

True... But for some reason it does

Does the hum problem return if you remove the battery? I'm trying to make sense of why installing the battery makes the power supply work better.

Actually no, it's gone for good...! Maybe the battery connector was touching something that caused bad ground connection or something...
