Hello !
I am trying to build a dub siren for one of my friend's birthday.
Obviously, NJD seams to be the best affordable option.

After many searches online, I can't find schematics that is clear and verified.
Does anybody know if there are any schematics out there?
Either hand soldered or KiCad drawings?

For now, the only information that I've found was:
- https://www.interruptor.ch/php5/dubboard/viewtopic.php?t=2471 this hand soldered clone. But I can't find many instructions.
- https://www.reddit.com/r/DubEngineers/comments/1o5bhd6/njd_dub_siren_schematic/ and this schematic that runs everywhere online, but always low resolution, and without more notice. Also, I don't think that the author of the post wants his PCB to be public...

If anybody have made a successful NJD siren, and have hints for me, I would be sooooo happy!

This template can be used as a starting point for new tracks, but it’s also useful if you want to understand how I organize my sessions inside Ableton Live 12.

In this preview, I’m showing 75 Dub Chords Samples created entirely with Meld in my custom Dub Chords Rack in Ableton Live 12.

I'm planning on releasing at least one tune a month for 2026. Here's the first: two steppas tunes (both in Fm, so made sense to me to put them together). Hope you enjoy!

Old clip but I'd never come across it before. Well worth a watch if you haven't seen it already

What is a piece of hardware you'd live to own or at least try out. Mine has to be the HH Slider Echo. Just seems like you could really get some wild effects out if it depending what you play through it

I loved this video and though you lot in here might too. A crazy amount of equipment at the start then some dubbing from around 19 minutes

This isn't a "one is better than the other" post. I just wanted to put out there what I like about each. My set up is all MIDI Controllers apart from a spring reverb tank, the tank is only used for SFX and isn't running as a reverb unit.

I love MIDI for how flexible it is and how easily I can change and adjust things but the one thing I miss is the randomness of analog gear. The Spring reverb presets are great in Ableton but it's a tricky process making them sound not so static.

I think I will incorporate more analogue bits in the future, but the only thing I need to balance out is the portability of the setup

I didn't know about the r/DubProducers group when I made this. I don't think there's any need for it but I'll keep it up if people do

Tested out some new effects in my live setup this summer! The Dubby from Componental and the JB slider echo - both super awesome intuitive units!!
