Trouble with Boss DD3 pedal

Gerry Grider · Post by **Gerry Grider** » 30 Nov 2001 8:40 am

I bought a DD3 pedal some time ago along with the AC adapter. After about two uses the light remained on but no delay. I sent it in twice for warranty service and they sent it back saying "use a battery maybe your adapter is bad". Sure enough delay worked with the battery. So I bought another Boss adapter and after 2 uses it started fluttering loudly and now no delay. Bad pedal or operator error?

Jay Ganz or some of the electronics guys on here need to answer that one for you but if it works with a battery it must have a bad jack or connection of the jack that the transformer plugs into. I can't see anyway it could be "operator error". I guess it is possible to get a faulty transformer. It the red light coming on when using the transformer? Another question just came to my mind. When there is a battery in the unit and a transformer plugged into to it also, what causes the unit to switch from the battery to the transformer or does it do that? Could there be a problem there? Where are you Jay?

Gerry.....

It sounds like you may have a short of some kind in the DD-3 pedal. You stated that AFTER 2 or 3 times then the device quit working with the adapter (but red L.E.D. did stay on). Did the A.C. adapter get quite warn(maby even hot) to the touch ??? If it does, that is a very good indication the pedal has a short in it. Now while the DD-3 does eat battries rather fast,this is not unuasal. Infact, everyone complains about this battery cruncher. If you can check the output of the adapter while it is connected to the DD-3, I would say the output should be in the range of 7 to 9 volts. If it is around 4 to 6 volts, I wouls suspect a short of some kind within the DD-3 pedal. The reason the red L.E.D. stays on is because that is a 1.6 volt/low current device.

Hope this helps .......

On the adapter, there is a tag stating the voltage and current rating. What are they? Also, the center pin of the plug must be the
"minus" (-) connection.

Hey Fellas,
I just recieved a BOSS RV-3 from MusiciansFriend, and in the instructions
it specified to use ONLY a BOSS AC/DC
adapter.

Is this just company bull to get you to spend, yet, more money? I have dozens of adapters laying around, so I certainly don't feel too inclined to buy another one.

Thanks for any help, fellas.

Danelectro makes a little 9-volt wall wart called the Zero Hum AC Adaptor. They actually put out 9.6v at 200mA. They retail for about $10 and they work great. I've got a couple of stomp boxes that hum, even when I use an expensive 9v 800mA power supply. No more hum since I started using the Danelectro unit.

That's right! $10!

Most of the time you don't have to use the Manufacturers branded power supply as long as you have one that has the proper voltage and current and polarity (and proper connector).

However, there are some units that require special power supplies such as some of the Ibanez that require regulated DC voltagepower supplies or units that have multiple voltage requirements and must have the power supply made for the unit.

Thanks Jack, and Lee.
I felt it would be alright to use any adapter
so long as you had the correct DC voltage set
right.
I just wanted to double check with higher-ups
to make sure, before I might put the 120v fizzle to the unit.
