All the different DD-3 models

Yes, the DSD models have the same long chip as the DD-2.

..and often can be found somewhat under the radar price wise. Well at least until recently. And I’ve never figured out the trigger sample bit

It is a very very, short hold function.

Not sure if you need to keep the switch pressed down like in the DD-2 or DD-3 to engage it. You would get a DSD pedal for the delay function instead of the trigger function.

I would miss the split out function in a DSD model. I think the trigger signal needs to be around +5V, not ground. The manual only says that the trigger input receives the signals coming from a drum computer for example.

Looking at the schematic, the trigger is signal of +5VDC

Ah, the stinkfoot article is really good! Thanks for the link, fernieite! So there are late Japanese pedals (all have the blue label) with the square chip (version 2a). I wasn't aware of that. The Taiwanese pedal that I mentioned has the internal PCB mounted adapter jack, so it's definitely a square chip model (version 2b).

Interesting. I always thought that the blue label was an indicator for long chip models. So far I was always lucky to find the big chip in the Japanese units that I bought over the years.

Yes, in the glory days of purchasing and reselling DD-3s I soon learnt this lesson! Which reminds me I still have too many and one or two in the repair box

I still recall vividly two times when I was much younger of observing band mates fiddling with blue label examples and being amazed by the sounds, back when they were about 90 pounds (2003-5 iirc). BOSS was unaffordable or “top of the tree” (even used), although the overdrives and distortions were admittedly ubiquitous. Around 2005 I purchased a unit in Japan, brought it back to the UK and it became my sound in the manner of the then popular Bloc Party*

*sidenote: the BP guitarist chap used about three or four of the DD series, “5”s in particular, had a humongous pedalboard and played with a Telecaster. A very thin brittle sound!
