I just bought a new pedalboard, so I rearranged it, and all of the sudden my Wah (which has been working fine without any unwanted noise [on a daisy chain]) started humming like crazy, and the distortion that comes after it amplifies the hum.

I have a Crybaby (the standard one) and a Onespot+daisy chain and I also have another 9v adapter to go with it. Any idea what the problem is and how to fix it? Thanx a lot.
Try isolating the problem... Is it the cord? Is the connector loose? Are on the bolts around the connectors loose? etc.

Come back once/if that's done.
Looking for my India/Django.
Try moving the power supply rectifier and transformer further away. Pretty common problem.

my buddy use to fix those and he says that its prolly the inductor and you cant do anything about it, sorry
