My wah hums

Post by Crow » May 14th, 2012, 7:16 pm

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.

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 :D

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.

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

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.

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....

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.
