So I buy this DD7 off some cool cat on Craigslist, it looks clean, has obviously been cared for, etc so I don't think I was sold a possessed pedal. This was like, oh, I don't know, a year ago? In the past 4 months or so, it's developed this weird kind of "radiophonic" element to it, where when I turn it on or off it makes this huge fucking pop and touching any part of the pedal makes the same aforementioned pop, like the thing is fucking ALIVE. Of course, the pops also hit the delay, so it sounds like a clown is shooting a shotgun full of ball bearings into a dead whale. While that sounds, cool, it is really harshing my mellow when I'm jamming with my bros and they're really starting to hate me when it happens. I also happen to really like the DD7 but I'm debating trading it, but I wouldn't want to own/sell/trade a defective pedal.

Troubleshooting report: So I've cleaned the jacks with contact spray, changed cables, isolated the effect from other pedals, changed power supply (I've tried a battery, PP2+ and a daisy chain) tried it in different rooms with different circuits, and the only thing that seems to temporarily negate this awful byproduct is ramming a patch cable into the mono in jack a bunch of times, but then sometimes this seems to work and sometimes it doesn't.

So is there anything else maybe I'm not doing? There is a fucking lot going on in that circuit board, so I don't really want to pull anything out. The synth player in the band I'm in seems to think there might be some wire touching the jack which is causing this, but I can't really get in there to mess around.

Does Boss have good customer service for this sort of thing? Would they fix it if I mailed it to them? Any other advice?

I'm no electronics expert, but groundwhore, sorry, typo, groundwire problem comes to mind...

That really does sound like a grounding issue somewhere.

... or one of the components has become microphonic or something?

You KNOW we're gonna need to hear some clips.

Can that happen? The devil is here!!!!

Is there a cap that's discharging to the wrong place maybe?
Maybe not earthed correctly?
Definitely some kind of grounding issue.

Clips for sure.

That clown shoots whale description was pretty much the funniest shit I've ever read regarding tone descriptions.

yeah, that can totally happen, but it's probably something simpler like maybe the jacks or the foot switch. I think that's more commonly the source of the problem.

Analog Man works on Boss delay pedals. Mods, really. If Boss doesn't work on old pedals see if AM can help you. www.buyanalogman.com

The DD-7 has been introduced only a few years ago and BOSS says "5 years warranty" on their boxes. Even if you don't have an original receipt for this unit I would recommend to contact Roland/BOSS. Explain what's wrong and maybe they can help you. I work in a small shop and I made the experience that most companies really care about their customers. Give it a try.

wut?

Yeah. In the music shop I have dealt with most of the big music companies (Roland, Yamaha, Korg, Fender, Ibanez, ...) and I can only say that the customer service is extremely good and generous in most cases.

I think it's supposed to be 'in my' experience?

Yeah, sorry. Non-native English speaker here!

Maybe it simply depends on the guys in the music shop who have to deal with the customer complaints. We have always been eager to handle these cases in the most satisfying and quickest possible way. I can just say that most companies have been very cooperative.

will trade for if actually possessed by the devil
