err...this is my first time here...so hi to all in the forum 
my problem is with my dd-3. works fine with batteries but when I use my adapter (which is not boss PSA by the way) the output gets screwy with all sorts of hissing noises....I've tried the adapter with my OD-3 and CE-5 and have had no problems...can anyone tell me what I'm doing wrong?
(I'm buying a 1-spot adapter, and am crossing my fingers that I don't have the same problem as this...argg...) |

Welcome to Bossarea eggs! 
Isn't the 1spot a switched supply? Some here at the forum don't like it much. I have 2 & think they're ok but an authentic Boss supply should be better especially when powering multiple pedals.
Anyway, standby.. others will pipe in & help. |

welcome to the forum...... ...i'm sure others more qualified than me will explain it better but from my experience with my DD-3's(i use two)i find of all the boss pedals that can have problems with spurious adapters is the DD-3,i don't know if it's because it draws a lot more than a overdrive or a chorus but i suspect it might...i had a zoom power supply that would work on all my boss pedals except the delays..the LED would come on but no effect while all the others and especially the ACA ones loved it... i went back to a normal boss adapter and no probs ever since.....i also noticed after a while that the zoom adapter caused a lot of the overdrives when turn on to feedback a lot more ...... so it had to go....... |

G'day and welcome!
According to the spec, the DD-3 draws about 50 mA - so current consumption shouldn't be a problem.
What it probably needs is a regulated supply. Most of the "normal 9V supplies" (like from a cordless telephone) are definitely not regulated. The Boss PSA is regulated, and it may just be what is needs. The 1-spot - while switched mode and thus to be avoided in my book <disengage rant mode> - is regulated and could well fix the problem.
Regards,
Laurie |

Hi ilikeeggs
Welcome to the forum from Australia.
Some early DD-3's were the same as the long chip DD-2.
And used an ACA 12V unregulated power adapter.
You might have a 12V pedal and not the later PSA 9V reg type pedal.
Check the little sticker next to the CD socket (if it's still there)
and tell us what it says.
Else open it up & see if it's the older type:
You can read about the 3 different types of DD-3 on Stinkfoot's site:

Thanks again Andreas

I think all DD-2s and DD-3s are 9V PSA pedals. The PSA adapter was introduced with the digital pedals like the DD-2 because they drew more power and required a cleaner power supply. The PSA adapter was 9V from the beginning and I think all digital pedals were made with this adapter in mind. |

Thanks
Franzoi, I forgot to add, the adapter I had WAS a Zoom adapter, coincidentally
Dr. Bob, I checked the sticker and it says to use boss PSA adapter , so I suppose it's not the ACA-PSA problem
The 1-spot arrives in a week's time, and I am hoping again that I won't have any problems...(or that's about $20 down the drain...) |

I'm guessing the DD-3 simply doesn't like the adapter you're using. Digital circuits can be picky that way, and I have yet to see a situation like this (with strange hissing/whining noises) where a good old Boss PSA adapter didn't do the trick.
bossarea is right, btw - the DD-2/3 has been a PSA pedal from the start. The relatively high current draw of this circuit, along with its relatively sensitive nature, ruled out the use of an unregulated adapter like the ACA.
