I have a problem my Boss DD-3. The first repeat comes much earlier, at half the time of the set tempo (in all settings). I've tried it both with and without a tap pedal. And it's always been used with 9V adaptor. This problem has come up recently and I can't figure out what's wrong? Thanks for any help! /Johan Jonsson

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

Could be the level from your guitar is too high OR low. Too low the tuner can't get reliable signal... Too high and the tuner will see harmics of the strings. Make sure you set onboard shape or EQ's flat. You CANNOT tune while playing CHORDS... A single note at a time please...

Press the "click" button and then set the tempo you want, press the "click" button again this will stop the metronimoe but is also sets the tempo in memory. The next time you press the "click" button it will be ready to go.

Anytime you press the tempo + or - it thinks you are trying to use the "Tap Tempo Function".

Hello!
I am not positive on this but I would try to clear all of the loops. Try holding the right pedal for about 5 seconds.
If that does not work, hold the right pedal for about seconds while you turn off the unit. Release the right pedal then turn the unit back on.
Hope that helps!

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.

Hi. I had the same problem and fixed it by clearing all the phrases. An explanation of how to do this is below (written by someone else, not me) But, expect your guide beat to now sound like a fuzz instead of a drum. This really sucks and there is apparantly no fix for the guide sound except to send it back to Boss. Good luck.

1. Start by selecting Phrase 1.

(if the 'REVERSE' or 'AUTO START' are lit press them off.)

2. Select 'INST & MIC' by pressing 'MODE'

3. Hold down 'EXIT' and 'AUTO START' together - at the same time, this should light up the green LED for 'LOOP PHASE'

4. Hold down 'WRITE' and 'EXIT' together
then hold 'WRITE' on its own
then 'WRITE' and 'EXIT' together again...as if you were clearing a phrase.

they should light up in red and flash, if not try a combo of section 4.

5. Repeat on all Phrases 1 - 11.

Find a local handyman, preferably one with electronics skills as well. Sounds like you need one that knows adhesives... DO NOT use super glue for any of this repair... it is too brittle and will soon break again.

Use epoxy for broken parts... JB Weld is pretty good.

You are probably overdriving the pedal. Reduce the amplitude INTO the pedal and AMPLIFY it more AFTER the pedal.

When digital conversion is done from the input and the input exceeds the input voltage capabilty of the A-D convertor, it effectively "flattops" just like your overdrive on a guitar amp.

Your guitar may be very "hot" having high output. One needs to keep the signal levels in-bounds of what the hardware can handle at EVERY point.

This may be he characteristic of mixing of the delayed when high distortion is present...

I would go to music store and compare... I tend to think this is the nature of the beast.

If you consider what the waveforms look like with distortion and then add them delayed... they limit out and when added there is a significant difference when adding or mixing waves that are delayed when squared compared to nice sine waves.

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.
