I just got an MF-103, and it’s amazing except for one thing: whenever I use it at my apartment I get tons of noise and radio interference. Any amount of drive or output past about halfway renders the pedal almost useless with noise. It works great at my practice space, just not at my apartment. I’ve tried tons of gear at my apartment as well and haven’t had a problem with a couple amps, my Little Phatty, other pedals, etc. Any ideas?
It is possible to electrically shield pedals with aluminium (or is that aluminum 
) foil. You could try taking the wooden side panels off and attach some. Obviously, be sure not to short out any components on the board!
Or, try a Faraday Cage
Yep, happened to me too.Try to run the wires somewhere else. You can also try to make a sort of Faraday cage around the circuit board (it didn’t really work for me to be frank). Alternatively try to move the box around in you apartment to find the position where you get the least noise.
Do you think it could be the power adapter? The one I’m using isn’t moog-branded, though all of the specs are the same?
No, it is not power adapter related. I tried with the original Moog power supply and the PowerAll (or whatever the name is) without any improvement.
I’ve noticed now that the interference is really only bad when I have my hand on or near the actual unit. Weird… Any ideas?
Well, you could keep a copper or aluminum plate next to the phaser, and touch that with one hand to ground yourself out while tuning the phaser with your other hand. Otherwise, I have no idea.
