Hello,
I’m not sure what happened…but it seems like the feedback knob only has a limited effect when the loop is on Internal. I can have it turned all the way up and still only get a few repeats. I remember having to REALLY Watch It when I had Feedback turned up that high.
I still have to watch it and the Loop Gain when I have it set to External Loop. Any ideas? Seems like maybe it is broken? If so, that would suck…because it was $700 and I haven’t even had it a year 
Mine did the same thing last year. I sent it back to Moog and they fixed it. It has been fine ever since.

Hello,
Mine did the same too. I was thinking about power supply problem (because switching it off and on sometimes correct the problem) but after opening the Moogerfooger what a surprise !
A 3 pins jumper selector on the left of the pedal, mounted on a second circuit board, is close touching the metal frame of the MF 104 Z 
When he touch the frame completly there is no more repeat !
I just bend the pins to avoid any mechanical contact and no more problem since …
Very disappointing for a Moog product
Thanks for the tip, mimich.
I addressed the issue with a small piece of business card stock and some electrical tape to hold it in place. 2 of the 3 pins had worn the paint right down to bare metal!
I thought it was a power supply issue all this time as well.
Can you be a little more specific about what needs to be done? Where is the second circuit board? How do you get to it?
Thanks,
Bryan
On the left side (circuit board view) or on right side of the pedal in normal position.
You can see an extra bord with jumper …
Isolate the pins from the metal frame or bend them like on the photo
what’s the official word on opening these up ourselves?
does it void any support?
is it simply as easy as ‘bending’ that piece?
thanks
I suppose that officialy this void the waranty, and this is at your own risk, but you can just isolate the pins if you’re affraid of bending the jumper.
4 screws to remove the right wood plate and an electrical tape … or send back your moogerfooger to MoogMusic
Well, you remove the sides to rackmount them, so hopefully it’s still okay.
a small post in note stuck to the medal on the inside is all it took for mine.. no lasting damage.. paper= excellent insulator
It turns out that this is exactly what the problem with my delay has been. If the jumpers touch the casing, no delay. If they don’t, it works as normal. I’ll send a note to Ryan at Moog that this is what is going on. I’ll see what he suggests as a fix.
Thanks for the thread!
Bryan
I woudl not bend the pins BTW
Yeah, that seems like an accident waiting to happen. Either a broken solder joint, broken pin, or something else. I’ll report back what Ryan suggests.
I’m just happy to be at the bottom of this, as the 104 is my favorite pedal. The intermittent problems were starting to sour my love for it.
Bryan
IF I were a service tech, I would probably just Nip the Tip… You know about half off.
I wonder what function the jumper is playing.
Half of me wants to tweak the insides to mod them (I like turning and tweaking things, thus I like Moog Stuff).. but I dont’ want to mess with the balance that is there on the internal pots…
While we are at it, any one know what each of the internal pots controls, or internal jumpers?
Hello,
The best solution is to use closed jumper caps (2 for hiding the 3 pins) like the blue one on the photo …
That was the gist of Ryan at Moog’s suggestion:
Clipping these pins is the way to go. Yes, remove the jumper and clip them so that when the jumper is replaced, they are not protruding and/or making contact with the housing. This is grounding out your signal.
I’ll do it tonight and take before and after photos.
Bryan
As promised, here’s what I did to fix my delay. I apologize for the cell phone pics.
Before: You can see that the pins coming off of the smaller circuit board hit the casing. This led to my intermittent problems.
After: You can see that the pins no longer touch the casing.
What you’ll need:
Phillips screwdriver
1/16" hex wrench
1/2" socket
wire clippers
patience
How it is done:
You need to take the delay pedal apart. Start with the bottom and the wood sides. Remove the knobs. The large ones pull off, the small ones have an Allen screw. Remove the nuts and washers holding the six pots in place. Unscrew the four nuts for the top row of CV and audio input jacks. Also unplug the small connector for the footswitch that runs to the main circuit board, as well as the connector that runs from the other four jacks to the circuit board.
At this point, you can remove the circuit board. Be careful and have patience. You don’t want to bend the pots/LEDs/switches. Also be aware that each of the nuts that you removed had a washer counterpart on the inside of the pedal (lock washers for the pots and plastic spacers for the jacks).
Now, the easiest part. Find the offending three pins coming off of the small second circuit board. Remove the jumper (remember which two pins it was on!). With the wire cutters snip off enough of each pin so that it will no longer hit the case when everything is back together. Replace the jumper.
Reassemble the pedal. Don’t forget to put the spacers/lock washers back on. Be careful when putting the circuit board back in, as you need to get the jacks in and then line up the pots/LEDs/switches.
Hope that helps,
Bryan
I wanted to update
I had a problem with mine before, which was corrected by unplugging and replugging the power suply back into the chassis.
Last night though I broke out my rack and was using the touchpad to control the feedback on the delay. It was working good and fine and then stopped working. I turned every knob and switch I could think of, tried the power supply trick and no more than 1 or 2 echoes.
It eventually cut itself back on and worked fine, but Im beginnig to question its reliabillity. If I was laying some tracks down they woudl be ruined.
If it happens again Ill contact Moog about an RME for a permanant fix.

I’d bet $0.25 that your delay looks like mine in the ‘before’ picture with the three prongs touching the casing, causing intermittent shorts. Pull off the right side wood panel and see if that is the case.
Bryan
I got curious and opened up my new delay that I got one week ago, and see:
it´s a little blurred, but you can see moog put plastic on the pins, so they don´t touch the casing anymore. they do listen!
btw, this delay is fantastique!
