EVH 5150III EL34 Ground Loop in FX Loop

[Geo]

If the noise went away with the short cables, the long cables are picking up noise.

only thing I can suggest next is to check solder points and PCB trace points from the Loop jacks to their next point. Aside from that, your next option may be taking it to a tech.

sorry couldn't be much help.

I gave it a visual and nothing looked unordinary. Thanks for the help!

How high to you have the channel volume set?

Mine pops sometimes when I engage or disingage a pedal.

Are all your pedals true bypass ? Or at least the pedals that pop are true bypass ?

Doesn’t matter. Buffered,true bypass, even my boss es8 switcher can make it pop.
It helps if I cycle them on and off first.

interesting.. that's usually a "symptom" of True Bypass pedals. I am surpised it happens with all.

I run every through a boss es8 so I can change the buffer before or after the pedals or both. Still pops every so often.
Doesn’t do it with the metro loops just the Evh loops. I’ve tried it with three different heads.

See my post on the first page re volumes are pre loop.

Any updates on this issue FondledDuck? I am getting significant noise when I engage the effects loop I'm my 5150-III 6L6 50w. To me it sounds like a grounding issue. I'm no expert but it is this type of noise that I'd always there when the loop is engaged but gets worse when holding a guitar and moving closer to the amp.
