Today i got a daisy chain power lead which I attached to my Zoom 9V Power adaptor and plugged 1 end into my Zoom G2.1u and another into my Dunlop Cry Baby. For some reason when it's plugged into my Cry Baby I get this (Very) loud mains buzz, more than any noise gate can handle, even louder than the guitar signal. When i unplug it from the Cry Baby and bypass it theres no buzz.


Can anyone help me out?

Here is a picture of the setup:

Try these two first:
Guitar > Crybaby (battery) > Amp
Guitar > Crybaby (poweradaptor) > Amp

If it buzzes both times, theres a wiring issue inside the wah (probably ground). It's a fairly common problem.

Tried the 2nd one, exact same problem. It's fine with battery (i think) but i can't afford to keep replacing them every 5 mins which i why i bought the daisy chain.

Heres a picture of the inside of the Cry Baby if you can spot any wiring issues. I can also upload a recording of the buzz if it helps?

I have a feeling it might be the power supply (too much power maybe?).

Shall i post a pic of the adaptor and maybe consider getting one of these or something?: http://www.ebay.co.uk/itm/Guitar-Effect-Pedal-Power-Supply-9v-5-Pedals-/270310792916?_trksid=p5197.m8&_trkparms=algo%3DMW%26itu%3DUCC%26otn%3D10%26po%3DLCA%26ps%3D63%26clkid%3D2102569454942561901&_qi=RTM742989

"I have noise"
"Get a noise gate"


Why do so many people think the best way to fix a fault is to paint over it so nobody can see it?

The most likely cause is that your supply is too small. If you pull to much current from a supply you get 120 Hz hum on the supply line. Add up all the power draws of your pedals and get a supply rated higher than that.

I only use a noise gate to get rid of a lil bit of mains hum, i don't use it excessivly though. This is wayy too loud to be covered up though.

I'll write up the specs for the adaptor if it helps.

if its buzzing with the adapter into the crybaby but not with a battery, id guess its either a power supply issue, or a bad dc input jack in the wah

EDIT: check the current draws on both pedals (should be written somewhere, or in the manual)

Guitar - Cry Baby - Amp

This seems to work with the Cry Baby on adaptor. It's when i go through the G2.1u with both on mains that i get buzz.

I seems that you need a power supply with a higher amperage (i.e. get an adapter that outputs more than 300 mA).
Dear God, do you actually answer prayers?

Yes, but only in a way indistinguishable from random luck or the result of your own efforts.

Ok, thanks alot.

This one says 600mA, will that be ok?: http://www.ebay.co.uk/itm/Guitar-Effect-Pedal-Power-Supply-9v-5-Pedals-/270310792916?_trksid=p5197.m8&_trkparms=algo%3DMW%26itu%3DUCC%26otn%3D10%26po%3DLCA%26ps%3D63%26clkid%3D2102569454942561901&_qi=RTM742989
