Venue - hum when using FX loop

[AlVal]

Hi
Any help or suggestions appreciated
using Venue with Align reverb patched into send/return loop
both using seperate one spot power sources
noticeable low end hum when reverb pedal patched
same when daisy chained
using swedish audio flat patch cables..
hum goes once rev unpatched from fx loop

when i touch the input cable from the guitar the hum subsides …

any help, thoughts or possible solutions appreciated

best

Updating
Warren from Baggs suggested to use truetone one spot when running the complete align series
as i’ve simplified things i figured the same power source would be optimum
i found an old Boss adaptor which greatly reduced the hum
Still present but workable
im not sure how noticeable it will be once i patch into some of the systems at festivals

both my guitars use the Anthem systems
the odd thing is when i place my hand on the output jack the hum goes
plugging the guitar direct into a system the same thing occurs
so im also questioning this

oddly hadnt experienced or noticed any of this when running the align pedals

still appreciate any input
and why the Boss adaptor has reduced the hum considerably

best
and thanks

Hey AlVal,
I replied to your email a little while ago. I think there's a chance that the hum is not related to the ground-loop in the pedals, but rather in the shielding somewhere else in the signal. If you want to email me back, I will do what I can to help.
