Re: Help! EDP output makes hum louder than my loops

Thank you Andy!

I thought I had ruled my amp out, but I guess I didn't. Anyway, the EDP is humming along nicely through a different amp now.  Thank you for taking some time to help me out.

hi Jack,

I'd guess the fault is the earthing within your amp,
not the edp at all.
(because you say zeroing the input volume doesn't kill the hum).

Philip's suggestion should work,
but your amp may be dangerous.

Ever hear of those scenarios where the guitarist gets electrocuted
when he touches the mic?

Yep, that could be you, suggest you get that amp checked out.

My Gibson EDP produces an insanely loud hum which I think is ground noise. (sounds like it)  I've narrowed it down to the output jack.  Even if my EDP is turned off, it will still make a really loud hum into my amp or computer.  Even if I mute my amp and turn all the gain down, the hum still comes through my amp at full volume. The input/output knobs don't alter the hum at all.  In fact nothing does, except turning my amp off or unplugging the EDP. The looping functions work fine and the looping material still comes out of the EDP, but it is a little softer than the ground noise sounding hum. Does anyone have ideas on how to fix this, or what precisely is making that hum?

Thanks for any insight,
