HX Stomp Noisy LEDs

Hi all

 

So, I've just updated my HX Stomp to 3.0, plugged it all in, and now I get an 80Hz(roughly a low E-string) noise whenever one of the LEDs are switched on. If I enable tap tempo on FS3, the noise is concurrent with the tempo... :-/ The noise is too loud to ignore, sadly, and I have a gig(FINALLY) on Monday.

 

Anyone else have this problem? I'm powering it off a Gigrig Distributor/Generator, using the correct adapter cable.

 

kind regards

I experienced this tap-tempo LED synchronized noise when I daisy-chained HX stomp power supply (DC-3g, the stock one) to power both HX Stomp and G70 wireless receiver. DC-3g has enough juice, but I suspect the supply voltage ripple due to LED on/off is injecting noise to G70. I switched to isolated power supply (Strymon Zuma R300), problem solved.

 

I guess Gigrig Distributor is non-isolated power supply, causing the same issue.
