Pedal Buzz

So I get a hum with my pedals connected..
I have a Boss Tuner, Dunlop Wah, Boss Flanger, Ibanez Tube Screamer, Line6 Delay Mod and EH Holy Grail. I have the AC daisy chained into the tuner besides the seperate adapters for the Line6 and Holy Grail then they connect into an extension cord into the wall.
I've tried them individually with two brand new, good quality patch cords and I still hear the buzz. Just thinking about it now I haven't tried direct power into a pedal instead of the daisy chaining but that's all I can think of...
My buddy thinks it might need a power conditioner? I tried a home theatre one from Walmart and it made no difference...
Any thoughts?

99% positive it is a ground loop. Very few amps made today have a ground loop switch on them. When I used pedals, I had a Whirlwind Direct box that had a ground loop switch and it made a big difference. |

I agree with Randy! Plus you check the following. You may want to start with just your guitar, cord and amp only first. See if the hum is present. Add one effect at a time to see which component is your culprit.
On other notes the shielding or jack connection on your guitar or any of the efx could be an issue. Are your power cables being crossed with your guitar cables? Keep them as far away as you can. You can use shorter cables for practicing or jamming at home. Good Luck! |

I'd agree. Sounds like a ground loop. What power supply are you using? or using one t all? (dunlop power brick, voodoo pedal power etc)
Try plugging you amp into an oulet at one side of the room and you pedals to another. I got rid of ground loop buy purchasing a diago power supply and pluggin the amp into a double plug/splitter in the outlet, an extension into the other side of the splitter and the power supply plugged into that. Seems to work a treat!
If you'r in britain I'd recommend checking out Diago for a power supply www.diago.co.uk
Long winded answer but hope it helps. |

Thanks guys, that's looking real hopeful! I need to swing by a music shop tomorrow anyways so I plan on trying out the Jim Dunlop DC-Brick, seems quite good for it's price. I just hope it'll work with my Line6 delay and my Holy grail with it's 1/8" connector...

I've used a "one spot" on and off as my pedal collection waxed and waned. I liked it a lot, but it may have been the reason my Line6 Modulation modeler quit working. (I don't know for sure, but this was 3 or so years ago.)I've had as many as 10 or 11 pedals powered by it, although not all at once...

I bought an AC adapter from Radio Shack as a spare for my Ibanez Pue5 multi fx board. When I tried it, it really made a hum but the original didn't. Probibly a 1/2 wave rectifier or not enough filtering I guess. Now, I made a regulated 9 volt power supply and use it with enough outputs for all my effects. Only one power sorce and it's clean.....Jack |
