Hello Line 6 community,
I am using an HX Stomp as part of a bigger pedalboard recently and have been able to play without issue at home. However, I did my first outdoor gig with it and experienced what sounded like a ground loop noise through the PA system when I was hooked up to the PA and pedal board. I bypassed the helix, sound was gone. I used only helix, sound was gone. Both power supplies for pedals and helix were on the same power strip.
I believe it is ground because the noise is consistent regardless of the output of the
HX (I turned the volume all the way down)
Anyone have any clues?
On a side note, I always get a hum when I use analog bypass. I am wondering if there may be something specifically faulty with my unit.
Thanks in advance
