ReeV0 Posted November 14, 2020 Share Posted November 14, 2020 (edited) Hi guys, Can anyone think why my pedal might be so noisy? Edited November 14, 2020 by jjl5590 Quote Link to comment Share on other sites More sharing options...
paul_5 Posted November 14, 2020 Share Posted November 14, 2020 (edited) sounds like you're drawing too much current from your power supply. Digital effects are notoriously Amp-hungry. Check that your supply can deliver the required amount of current through each of the outputs. Also some supplies don't like reliving current to a mix of analogue and digital devices at the same time.

paul_5 Posted November 14, 2020 Share Posted November 14, 2020 Do you have a spare 9v output on your 'isolated' supply? you could buy a 'current doubler' which effectively runs 2 9v outputs in parallel (still 9v, but twice the current, so effectively a whole amp).

The power supply should be more than capable of supplying all the power the pedals need, it's a Mosky ISO 10. I also tried plugging the SDRUM into a separate 9v adapter.

There are lots of spare outlets, I'm running a current doubler for the Stomp (500mah x2) Quote Link to comment Share on other sites More sharing options...
Hellzero Posted November 14, 2020 Share Posted November 14, 2020 Do you have a modem, a WiFi device or a PLC nearby or plugged to the same socket ? This sounds like this plus a ground loop. Did you notice that the noise gets stronger when you came closer with your smartphone (it's in your video) ? You have the starting point of your answer here. 1 Quote Link to comment Share on other sites More sharing options...

Teebs Posted November 14, 2020 Share Posted November 14, 2020 (edited) Sorry Hz, was distracted! Regarding the problem, I agree with the right-honerable Hellzero - I had a problem similar, so after some research, I bought this: Mains conditioner - solved my problem. About £50, although you can spend loads on fancier gear if you are so inclined. Edited November 14, 2020 by Teebs Quote Link to comment Share on other sites More sharing options...
ahpook Posted November 14, 2020 Share Posted November 14, 2020 When you make the two units share an earth, either via the cable that connects them or by touching their enclosures in the right way, the noise starts. That sounds like a clue. No real suggestions though...I hope you get it sorted. Quote Link to comment Share on other sites More sharing options...
ReeV0 Posted November 14, 2020 Author Share Posted November 14, 2020 I think it's an issue with the Mosky power supply... I just tried using my Diago daisy-chain power supply and it was still noisy but not as bad, then I plugged the Stomp (most power-hungry device) into it's own power adaptor and voila! No noise at all! So... because I'm OCD and I only want to have one plug to power my whole board, I've just dropped a bomb on the CIOKS DC-7 power supply in the hopes it will put this issue to rest once and for all... 1 Quote Link to comment Share on other sites More sharing options...
