Well I knew it was broken, thought maybe I could fix it and save a couple of bucks.

The pedal works in that when you strum something it delays, but after the initial delay the trail becomes distorted and very fuzzy.
Also when the pedal gets plugged in up turns on by itself, I think its got to do something with flipping a resistor or something.

Does anyone know if this is fixable?

Hi TomCray

Not wanting to sound like I'm fobbing you off.
But the DD-6 should still be under Boss's 5 Year warranty.
Perhaps I'm wrong about the warranty.

If not ask the seller, if they will tell you what might have happened to it,
just before it went faulty.

And as I've stated in a few other recent posts, these newer pedals are SMD, & making it a bit more difficult to perform repairs on.

Are there any obviously hot-brown-blackened area's or part on the little fellow?

I know this is a stupid one.
Is the insulator in place between the back of the PCB & the metal plate?
I had a pedal here, not to long ago, that was missing the insulator.

I had a pretty good history when it came to alleged broken pedals, I resuscitated a PH-1, TR-2, and LS-2, so I thought maybe I might be lucky this time.
This time I wasn't thinking when I bought it. Completely forgot that it wasn't a pile of resistors and caps, but those chips.

I really don't care if this thing gets fix up or not, mostly I bought it to scavenge some parts, but thought it would be cool if it got fixed.

Oh well.

What!! you're giving up already.....
Shame on you, send in some pics of the area around the power socket.

Get out your best Magnifier or specs.
Find a bright spot, or go outside on a nice day.
Look for bad solder joints, wires, anything that looks abnormal.

These are all Lead free solder if I remember correctly?

Nah, I'm not going to quit on this just yet.




Seeing as how this isn't usable currently I took it apart, I'll keep it apart as long as its needed.

After I poked and prodded the problem actually decreased, its still there and renders this delay unusable, but I have a better feeling about it then before.

Anyone out there know of any way to fix this, or if someone out there is selling some DD-6 guts ?

I THINK I FIXED IT!

Bored out of my mind I decided to do something rather stupid, I took off the cover, plugged it into my amp and started to mimic circuit benders, I took a cable and started to rub both ends onto the solder side, after a while I realized that the fuzzy static that trailed after the initial delay stopped and now I have a functional delay!

Don't know how long this is going to last, but I hope forever!

I'm stoaked

Hi TomCray & Guys

I sure wish I could fix stuff that simply.

I wonder what you actually did to make it work?

Congrats by the way.

Haven't the slightest. But I did "fix" it before but once I tried to put cover on it went back to normal. I'm guessing it could still be broken but its just hanging on a thread.

All I need is to get my $35 worth, and I'd be fine.

You have a dry joint or an almost borken wire sounds like...

Hi TomCray

Dumb question? So please humor me
Is there a plastic insulator sheet between the metal back plate & the PCB.
Some people don't put these back, for some unknown reason,when they sell - get rid of their pedals.

I could have made myself clearer. It was all fuzzy and distorted, once I messed around and fixed it I tried to put the plate (and insulator ) back on, but it went back to be fuzzy and distorted. When I fixed it again I tenderly put the cover and insulator back and it hasn't messed up yet.
