NPD: Boss DD-20

Great score Dave!
Like was said, trading away stuff you were not using for something you do is a WIN!

Speaking of delay:






(long pause)















I just ordered another Joyo pedal in my cheapy exploration of pedals:

I can piss away $20. on worse things.
The drilled enclosure with jacks and knobs is worth 8-$10.
I can always stick another diy fuzz board in there!

& that $20 would leave your wallet without delay...
 
I have been experiencing some noise problems running this DD-20 into a DM-2W in my effects loop.

Reading now that the DD-20 can be switched from -20dB to +4dB output level, and that mine would be on the default of -20dB. It seems that in an effects loop you need to set it at +4dB, so that might be my problem.

I am guessing that this does not affect some other delay pedals because those pedals have a fully-analog signal path, whereas this pedal obviously has a digital aspect to its signal path (if you can change the output relative to the input).

I would need to switch mine to Output Mode 3

What kind of noise problems?

Incidentally, the -20 db vs. +4 db level has nothing to do with whether the pedal is analog or digital. A digital pedal only processes the signal digitally internally. The physical inputs and outputs are still analog. The pedal has analog-to-digital and digital-to-analog converters on the inputs and outputs, respectively. I don't know the circuitry on this pedal, but very possibly all that's really happening with the lower level output is that a pad is being introduced to the output to lower it's signal level. Another approach would be to amplify the signal when the +4 db setting is selected. But, the simpler method is to use a pad.

As for which level to use, I'd stick with the lower level in your amp's effects loop. The +4 db level is considered professional line level used by devices like professional mixers, recording equipment, etc. All things being equal, +4 db signal would have a better signal to noise ratio. But, I would assume that your amp's effects loop is built anticipating the usual level of most effects pedals, so it likely expects the lower level. I mean, you can try the higher level to see what happens. But, that may not be your fix.
 
Well this is the other relevant page in the manual:

But I haven't tried it at +4dB and it might be the case that the Peavey loop is low level and the default is appropriate, with the noise issue coming from something else. The other culprit could be a 9V cable. I suspect if that's the case the issue might be with the DM-2W rather than the DD-20
 
Those asterisked statements are the key. You want to match what you have. But, if you're running the DD-20 into another device first, the output level of that second device is what the amp's loop will "see". The +4 db setting won't be seen by the amp. It will be seen by the DM-20. It's possible the higher level from the DD-20 may overdrive or distort the DM-2W.
 
Looking at the specs on the Peavey effects loop, level is -10dB, so I am guessing the lower level is appropriate. As DD-20s are sometimes used on keyboard rigs that might be one reason why they include the +4dB option. That and the fact that some amps use line level loops

Yes, getting rid of something big that you don't use for something small that you will use is win-win!

I might get rid of the DD-7 eventually. Not saying that I wouldn't replace it with a different delay though. It's just that many of the delays on the DD-7 are the same as ones on the DD-20

Dave have you ever played a Dan Electro Dan -Echo? They were made back in the 90's. I have one and must say that after all these years it is still my favorite.
