I recently bought a SDD 3000. I'm very pleased with the features I've used so far. It's going to take me some time to understand all this pedal can do. One problem that is puzzling my is it adds a lot of noise to my signal chain. I've tried changing cables, moving it's position in the chain and even using it alone. Is this common? Should I have all this extra noise? My go to cable is mogami, so I'm not using cheap cables. I just don't understand where the noise is coming from.
Thanks for reading!

Although I've run the signal without itand still gotten the hum I am using a Boss Looper pedal, after the SDD 3000 then to a Soundcraft MFXi 12 board and that feeds a Bose L1 model 1S.
Just checking the Input and output attenuation I found I had not set the input to the lowest setting, but did have it on the middle +16db with the input knob set at 2 the output was set to the lowest setting. That could account for some noise, but I don't think all of it.
When I ran it Instrument, to SDD 300, to Soundcraft mixer to Bose I still have a hum. It is significantly reduced, but it's definitely still there.

If hum is the main component remaining of the noise that can be heard, there are several possible sources. If you think the SDD 3000 is contributing to that hum, moving it (and the other effects units) away from mains power cables, and from other units with transformers in them might reveal the cause.
It's also worth checking the jack sockets are in good condition, and all their ground connections are secure.
If the hum is still there, the mains power supply for the SDD 3000 might be a source of hum. Feeding the SDD 3000 from a smooth 9V supply e.g. from a 9V battery might tell you something. (If you try this, take care because the centre pin of the plug that goes into the SDD 3000 is negative, whilst many, if not most electrical goods use centre pin positive. A PP3 battery probably won't be man enough to power the unit. A PP9 would be more suitable).
