There are 3 version of dd-3, version 1, version 2, version 2b, version 3. You can read the Difference on this link: http://www.stinkfoot.se/andreas/diy/articles/DD3.htm . My version I THE FIRST!

As the name suggests, is a digital delay!
These are CHARACTERISTICS:

A battery-9v, 9v adapter jack
-4 Pots (effect level, feedback, delay time and method)
-Mode: S.50ms, M.200ms, L.800ms. (Or 100ms = 1sec) and Hold mode
-1 Input, 1 output and a direct output (dry)

It's simple ... Boss is <img class="smiley" src="https://fr.audiofanzine.com/images/audiofanzine/interface/smileys/icon_wink.gif" alt="wink" />

UTILIZATION

It is very easy to configure!
I start with and then choose how Delau time feedback and then I finish with the level!
Hold mode is a bit harder to understand but when you can mairise well without it!

SOUND QUALITY

The dd-3 is known to be one of the best delay, then yes it sounds good trs! It's a bit more digital than analog, but the cold ... Ben is just a delay! There is nothing wrong with this endearing little PDAL <img class="smiley" src="https://fr.audiofanzine.com/images/audiofanzine/interface/smileys/icon_lol.gif" alt="" />

OVERALL OPINION

The DD-3 sells for $ 150 can. about. It's expensive! I buy a guy a break for $ 30 can.une joke! I rpar (just a diode that was his job, the guy had too powerful an adapter plug in and the diode to burn and the rest of the circuit being protected!) So I had a DD -3 for a fraction of a new one.
Basically, the pedals suitable for all styles and all! It is solid and is a good investisement for those who will pay full price!

Voil no doubt that this is a good trs pedals!
