Noise from amp when I'm using new pedal...?


Disturber

Question

Posted

The problem:

I recently bought a Supa Puss delay. When I put it in the pedal board, it's sitting in its own loop, from the loop pedal, and it gets quite noisy. And there is a low humming sound that comes at the same intervalls as the delay is set at. The sound is there even if the loop is turned off, for the delay. 

Every pedal is connected to the same power supply in my Warwick pedal board. I tried to put the delay in various places, and to shift the contact in the power board to different places. 

I discovered that the delay only makes noise when the Tonebone PB1 buffer/boost (http://www.tonebone.com/bigshotpb1.php) is attatched. It is placed first in the signal chain. These two pedals does not seem to like each other. 

Is there a way I can get rid of the noise? Is this a ground problem you think? Or something else? Any ideas you have that I could try would be appreciated.

Sounds like there is a electric ground problem. At least humming is always a good sign to this direction. 

Did you check polarity of your power supply connections? Are the conflicting items electrically equally powered? Did you swap power supplies?

I figured it's that using the same power source can be the conflict. Both pedals are using the same polarity. 

I have not tried another power supply for one of the pedals. The idea with the pedal board is to use the built in power supply for all pedals. I really don't want to carry around a separate power supply for just one pedal.

What amp are you using?  You're not using your Metasonix F'n F'r when this happens, are you?  The instruction manual says it does weird stuff sometimes, like a cascaded amp does, not to mention the mondo gain.

Edited to add:  No, I don't have one of those amps, but the Metasonix YooToob clip and instruction manual PDF file you posted a link to sure is entertaining!  ;)

Have you tried using a battery in the Supa Puss to determine if it's a power problem?  Does your power supply have isolated outputs or is it a daisy-chain style like the One Spot?

I will give the battery suggestion a try. The board has isolated outputs I think, they all come from separate connections.

You had mentioned that they're all connected to the same power supply.

Does the power supply have individual p/s outputs with voltage selection, & voltage polarity reverse switches?

Check to make sure the polarity of all the efx power connections are correct.

Same supply. Individual outputs. I assume polarity is the same, (boss style) or the pedals would not work?
