Voodoo Lab

Hi,
i got a GCX Switcher recently and are having some troubles!! When i plug directly in the the GCX everything is great, no amp hum, tone loss anything. It works how its spose too. BUT When i plug my guitar into a tuner or wah before the GCX im getting a major buzz!!!
My input set up is similar to the diagram below.

If anyone knows what could be causing the Buzz please HELP
Thanks

First, go back to just the GCX and confirm you have no buzz. Then add the wah to the path and see if you get buzz. If not, add the tuner and see if there is buzz. One of those pedals is creating the buzz. How are you powering them? Battery? AC? It could even be one of the cables you're using to connect the pedals.

Thanks Cudbucket,
I think it was one of the power supply's causing the buzz.
