My beloved old Thomas Organ Co./Vox Cry Baby is beautifully quiet with a battery under the hood. With 9v adaptors, it hums.
I searched for "pedal hums" in the forums & got nothing useful. If anyone has any ideas, I will be grateful.

Re: My wah hums
I know why it hums.
It's because it doesn't know the words.
Sorry. Old joke. In fact, really old joke. Just couldn't resist

It's probably hum from the Ac source. You might have a bad transformer in the adapter, or you might need a better one. Use the battery.

Re: My wah hums
You might try to plug in to an outlet that is on a seperate circuit from your amp. Sometimes this can help.

Re: My wah hums
i had that issue, so i got one of those connector things that goes from your power source to the 9v hookup instead of to the input jack.

Re: My wah hums
My pedal is pre-input jack. All there is is the nine-volt clip.
I'll try it with an adapter at next band practice, on an outlet I know to be grounded and quiet....

Re: My wah hums
Make sure the phase is right. Had the same problem with my ancient Maestro Fuzztain, even though it had a (mini phone plug) jack for a power transformer. Turned out the solution was reversing the wires so negative and positive went to the "wrong" parts of the jack, like the original Maestro power supply did. Instead of the "standard" tip= positive, sleeve=negative, it expected the positve on the sleeve and negative at the tip.Crow wrote:My beloved old Thomas Organ Co./Vox Cry Baby is beautifully quiet with a battery under the hood.
