Hey,
I am building a pedalboard around my Helix Stomp. I want to power it up using the power adapter attached to my pedalboard (Harley Benton PowerPlant - https://www.thomann.pl/harley_benton_powerplant.htm) I also bought a cable for that which doubles the current from two Power Plant 9V outputs (Voodoo Lab HX Curr. Doubler Adapter PPHX - https://www.thomann.pl/voodoo_lab_hx_curr._doubler_adapter_pphx.htm). Stomp turns on normally but I can't get any sound from it. There is no sound in the headphones either. Once I switch back to the original Power Supply everything works as it should. Whenever I connect it back to the Power Plant the sound is gone. Anybody had a similar problem maybe?
