Plug the Vox Stomplab into the furthest right power plug..it outputs at 9v 300mA. Right now you ahve it plugged into a 9v 100mA socket and your pedal requires a 9v 200mA power supply.

Sorry but it would only let me upload 1 at a time.

I don't know why I didn't try that

Things to always remember about power connections with pedals. Always know whether the sleeve or center terminal are positive, always stick to the rated voltage, I.e. 9V pedal needs 9V supply, 12v Pedal needs 12 v supply.

You can always supply more mAh than your pedal requires, and even daisy chain if it has room to spare. But you never want to supply less milliamps per hour than your pedal requires. Always good to know exactly what kind of current draw a pedal you plan to put on your board requires as well.

Glad I could be of help.

Oof. Thanks everyone else .

Glad you got it fixed.

thank you everyone for your help. Now if you can figure out what's wrong with my Ampeg. I have another thread in amps and cabs.

In my pedal chain, which goes Bass, Stax 5 band eq to Boss ODB-3 Over Drive to VoxstompLab IB muti-effect to Radial Big shot ABY to amps. My Vox squeals while under AC power. If I use battery power it doesn't at first thought it was daisy chain power supply. So, I bought an Isolated power supply. Stayed the same and I've tried every possible configuration. I still get same issue If it's not in chain by its self it doesn't do it. For the life of me I can't figure it out.

Had a similar issue with a line 6 m5 which is another high draw digital
Multi pedal. My guess is you’re not using the correct cable for the isolated power supply.

I have had a few pedals that created a digital feedback sound.. changing the gain structure fixed it

Pedal Squealing = Pig Tone.
What’s the problem?
