Noise on Moyo volume pedal

Benjamin Poilve · From: France

Hello all,

Last December I acquired a Moyo volume pedal. I am very pleased with the product, really well built and fits right into my case. Once accustomed to the size, it's really nice to use.

However, for a couple of month, there is some noise. Specifically, a light scratching when pulling back the pedal fast (for example for a "choke"). In the band mix, this is below the noise, but rehearsing at home, this is very annoying. I try to play everyday, but to say this pedal has a couple hundred hours of use is a generous estimate.

So what should I do? Change the potentiometer (I've heard that once a pot starts to make noise it can't be fixed)? Is that expected or a just a bad part?

Thanks for the help !

Have you tried it using another amp? The noise you describe sounds like DC leaking from the amp input, or possibly from another pedal.

Thanks for the advice !
I don't have another amp to test, but switching with an old Ernie Jr. and no noise can be heard.
I'll try to reach Glenn.

You might try using a electronic spray cleaner like Deoxit to clean the pot.

Please let us know what Glenn said - curious to know what our Moyos might encounter....

I've been in touch with Glenn, who from the start have been very helpful.

Basically, what seems to be the issue is that I have a bad grounding on my flat electric network. It leaks into the pedal, and since the top and bottom metal part are not connected it creates the noise.
When I experience noise, creating an electrical contact between both parts gets rid of it.
So my fix will be to add a Dunlop JR-style electrical connection between the top and bottom parts.
Glenn have been offering to replace the pedal with one with grounding, but I'll be handling this myself. Top notch support all the way !

Hey Ben, I know this is an old thread but I'm just checking to see if you were able to quiet your pedal down? I have been having similar symptoms with my Moyo but it doesn't seem to make a difference if I add a jumper from the top plate to the bottom housing.

I found that an older Moyo I had developed a scratchy squeak that was solved by a drip of oil...I don't remember exactly where I needed it, I think it was the bushing that the string goes around....

I have a very early Moyo pedal, number 012, from Glenn's first batch. It developed a little scraping/squeaking noise that turned out to be the spring rubbing on the wall of the housing. I fixed it by sliding the little string pulley away from the wall slightly, then slipping in a small, thick nylon washer to keep the pulley in its new position. (I cut the washer so I could just push it onto the axle.) The relocated pulley moves the string, and the spring, just enough to prevent the rubbing.

Glenn's newer pedals have the string anchor (and the string and pulley) in a slightly different location. This brings the spring away from the wall so it can't rub.

I have three of these pedals and use them all. I haven't had any other noise issues, electrical or otherwise. I'll keep the ground wire fix filed away in my mind, though, just in case.
