Wah or whammy noise! Need Help!

[kissing]

Hi All,
when ever my whammy is in my effects loop, and whenever i switched on my wah(crybaby), the noise is unbearable. and if the whammy is out of the loop, my wah stays quiet when on. Can i know why is this happening? Also, this happens if my computer is on, and quiet when the computer is off. I have tried connecting the power supply to another room and using an EMI filter but it still sounds as noisy.
Neeed HELP, thanks!

You might of pluged it in back wards, i.e. guitar in the amplifier input and amp to your instrament input.


How do you setup your fx loop? im having trouble setting mine up.

You were not clear about your wah. But run the wah and whammy in front of the amp not the loop.
But that is most likely has nothing to do with the noise. Sooo

If you are running the wah or the whammy with a power adapter try running both units on batteries might be some sort of ground loop issue. And how is the whammy if you take the wah out of the equation?

As for the computer causing noise is any of your gear close to it? I'm talking two to three feet? Using good cables? does your guitar have single coils? Does the noise change if you walk around the room with the guitar?

I think i did not mentioned it in my first post, sorry.
My wah and Whammy are in the front and not the fx loop, my effects loop meant my chain of effect, apologies for the confusion.
I have tried batteries for the wah, its not doing any good. the whammy can only run on AC.
There is no problem with the Whammy, its only with the whammy in the chain, the wah turns noisy.
The computer is in another room, when the computer is off, everything goes quiet. i am using mogami cables.
