Extending my pedal quiver and since I just recently bought a PSU, I don't really feel like getting another one. Decided to try to daisy chain them. Turns out two of my pedals have DC outputs, so I tried to connect one through the other. Got a horrible, whining type of noise. Disconnected and reconnected through a daisy chain cord - noise gone. So, I'm happy the problem is solved, but anybody wanna shed some light on what happened? The PSU has all outputs isolated.

Re: Ground loops or something else?
Outputs on the supply may be isolated but running a daisy chain doesn't isolate the pedals connected to it from one another. When you plugged the pedals together are you sure you didn't plug a DC output into a DC output (or input to input).?

Ya, fairly certain. Double and triple checked.--------------------------------------------------------

Re: Ground loops or something else?
Is one of the pedals a digital unit? They often need an isolated power lead (not daisy chained) otherwise they get feedback from the other pedals. That Pedal Show did a demo of this, I think - let me go look.

I think it was this one https://youtu.be/4XRCjHxaYkc
I'd suffered from noise on my board right up until I watched this, and separated out my digital pedals (I use a TRex Fuel Tank Chameleon) Now it's much, much better.

Which is why many people play electric guitars but very very few of them are actually musicians.

Re: Ground loops or something else?
Usually daisy chain issues are caused by a particular pairing of pedals. I've chained 5 pedals off of my Pitchblack with no issues, so there must be something about the NS-2 that doesn't play nice.

Re: Ground loops or something else?
Sometime the noise can increase or decrease with different outlets or different buildings. I've had pedalboards hum louder than the guitar signal at some clubs with sketchy wiring.Administrator of the SDUGF
