I haven't been around much anymore, but here I am for now. I'm busy planning a wedding AND moving into my new condo. Yeah, I bought a house and got engaged in the same weekend. (that was about a month ago)

Anyways, Ive begun to dabble in pedals and pedal making and electronics. I was given a DOD Flanger. It doesn't work. Basically, when it's plugged in and such, it emits a loud buzzing, very much like the sound you get when you touch a live cable jack to something metal and that big honk-like buzz comes out of your amp. It's almost exactly like that. It doesn't matter if the unit is on or off...same thing.

I was thinking it's either the switch, or the ground wires. Does anyone know what could be causing that sound?

Even though I'm a EE, I find playing time usually is more important than time spent fixing FX. I routinely toss bad pedals into a "might be vintage someday :roll: " box in the attic. So far it has a Crybaby, old Tubescreamer (!) and recently, my beloved Line6 DL4 (replaced with Echo Park!). But cracking a bad one open for a look is always a first step before abandonment. Based on what you've said, I agree: Check for a broken ground connection on either the input or output jack. The switch doesn't usually switch ground, so it's not likely -- but hey, a visual for anything broken sometimes catches an easy one.

I really only want to repair it for the experience of doing it and hopefully learning more about electronics. That's my main goal. I've opened it, and looked inside, and nothing seems to be out of place or broken. I will replace the jacks, check the wiring again. I may consider taking an afternoon and just taking the whole thing apart and rebuilding it. Remember, fixing the pedal itself takes a backseat to learning more about how pedals work. I've read articles and whatnot, but i learn from doing hands-on things. That's what this project is all about.
