My micro POG sounded great when I first got it, but after a year or so it started with the white noise faintly, growing worse and worse until the signal was barely audible over the hiss. I realized my warranty was past, and my electronics guy said he couldn’t do much with it since it was all digital, so I took a chance and cracked the casing open myself. What I found on the underside of the circuit board was flux, and lots of it. Turning brown. That is, oxidizing. I cleaned it up as best I could with solvent and a cotton swab, and it sounded much better–for a while. Now it’s getting noisy again. EHX, have you got anything to say about this? I’m no electronics wizard, but it would be a pretty big coincidence if the pedal just so happened to fix itself accidentally while I cleaned the flux off. Aren’t circuit boards supposed to be given a solvent bath or something to remove that stuff so that it doesn’t oxidize and make bad sounds? This seems like a fairly common issue with these. Hopefully this sheds some light for somebody…
