Question about BOSS AUDIO SYSTEMS Boss Dd-3 Digital Delay Pedal

1 Answer

My boss dd-3 pedal only works with a 9v battery. When I hook it up to the 9v apaptor, (a boss) it freaks out and does nothing. Can you help? Everything seems solid. the jack doesn't wiggle or anything.

    Thank you for your quick response! The adaptor is fine. I use it with other Boss pedals and no problem. I removed the back of the unit to see if there were any loose connections, but everything seems solid. It is so weird, I have been playing through it all week, left it alone for @12 hours and when I tried it , it wouldn't work!??! Strange! Thank you again for your help! I'll keep burning candles and howling at the full moon!

You will have to test the adapter with a volt ohm meter to make sure it is putting out the proper voltage. It should be as close to 9 volts as possible. Also make sure that thehole in the plug is negative and the outside is positive. Is it the right adapter? I don't have a schematic for this model but www.schematicheaven.com has one for a DD-2. Hopefully they haven't changed too much. If you decide to repair it yourself, check the adapter first then check for a bad solder joint where the adapter plug is soldered to the circuit board. Hope this helps somewhat.

Battery problem


DId you remove the plug from the input jack to turn the pedal off? If so then you may have a bad input jack.

Why is my vintage boss dd-3 very quiet on the repeats even when level is turned up full?


Assuming you have the feedback level turned up....can you hear any difference at all when adjusting the feedback?

My boss DD-3 makes a strange tapping sound on all modes. tapping sound gets more frequent when i turn the delay time pot to the right. its like a little tap sound getting into the circuit with the guitar...


Check your power source or battery. The sound is probably due to the internal processor recycling due to watchdog timer. If power is OK, then service will be necessary to repair the problem.

The Auto on my Boss RC2 sometimes doesn't seem to pick up a signal and engage. It is plugged into a multi- socket adapter and I do not have the amp turned up too loud as the room is tiny. I thought it was...


Sometimes, with BOSS pedals, the battery must be disconnected before using another power source. I ran into the same problem with my DS-1 distortion. If it's not that, then check the power rating of the power adapter. It should read, for the output, exactly 9V DC. If it doesn't, then you have to get a power adapter that has that same rating. Boss pedals will not use anything other than 9V DC (I know, I've tried).

Hope that helps!

My DD3 pedal doesn't work. Checked the battery and the adapter. The light won't go on it will only light momentarily when I click through the modes. Any help would be appreciated. Greg


Check all connections including the battery clip if you use a battery, and the adapter jack if you use the AC adapter. Also check you guitar cable connections as the pedal turns itself off if the guitar plugs have a loose connection. Make sure the guitar jacks on the sides are tight and don't need tightening. Any of those issues could cause the pedal to operate sporadically or not at all.
It could also be and IC problem internally on the pedal's circuit board, but before you open anything, check all the connections non electrical issues can occur more often on pedals.

My light turns on, can't switch it off, no effect or signal coming through at all. It appears to be in in working condition, just don't know what is going on.


First thing is to check that powr adapter is the correct one and/or battery is good. Light will come on with near dead battery or wrong power adapter... Wrong adapter can damage the unit.

My MT-2 wont distort my guitar.


A few things to try....

Usually the adapter will over ride the battery when used.
1) Make sure your 1/4" cables are working properly without the pedal "in-line".

2) Take out battery, and use just the adapter only. Make sure it is the correct and proper adapter that works with Boss. Usually the PSA-120. If you are not using a Boss Adapter, make sure yours is a direct replacement with same specifications. 9V/200mA. And "tip negative". DO NOT use Radio Shack stuff, nothing against them, but there adapters just don't mix well with Boss products and the like.

2) Try just the battery, no AC adapter. Remember to unplug the input when not in use. Saves battery.

Basic rule of thumb...when using correct AC adapters for all your pedals all the time, and all sounds good, then take out the batteries.

If you still experience problems, it would be an internal IC chip most likely. From there post another question maybe.

My boss digital delay works when engaged but no sound when not


sounds like the true bypass line has been damagd. Should be easy enough to fix. Pop open the unit and do a visual inspection first, if nothing is noticeable then do a continuity check with an ohm meter from input to output with the delay efffect off. If you don't read a short in this situation then your problem lays within the signal path and its switched path.

My Boss DD3 just beeps and nothing else when i turn it on


If you have experience with electronics you could take it apart and use a multimeter. My guess would be one of the delay chips but its something hard to diagnose without taking it apart. An audio tech could help you out. Chances are it would be a pretty cheap fix. Unfortunately Boss pedals are almost entirely surface mount so replacing a component or two takes more skill than the average pedal.
