ps, sorry if I sound like a grumpy git sometimes. reggae is and has always been my passion. Its a creative playground for me. it got me into building an amp, siren, speaker cabs and riddim to bust on it!
 
I love hearing/seeing the creative input by other people. It inspires me.
 
Keep it up
 
Love

In facts its not even a 100% copy.
If you check the schematic, and also the siren from the Japan guy, you`ll see that he has more switches/buttons the the NJD.

Also the transistors are not the original ones, even if that is not affecting the sound.



just my two cents, this happend long time ago in the soundsystem buisness, JTS is a clone of the NJD with a Sirene generator IC added.

Lincoln has cloned the Links SEG 1, and so on.

Hi,
the transistors does affect the sound...i've tried a lot of diferent combinations, from old germaniums to classic BC's...  depending of the transistors, the overall style is still an njd but...with a particular colour and  response in the shapes...
also there is some easy improvements and bendings to do that offers new sounds to have an "unique" siren...pots instead of selectors...etc etc....
like Rigsmith it tooks me lot of time to draw my own schematics, i opened and cloned a tubby's and a dubsonic and make my own mix from both...  i started to experiment with transistors because values were erased on some "commercial "pieces i opened...
for me an "online" shematic is a good thing bacause now we'll see some new improvments of this classic killer siren... even if the Japanese schematic is not the same than mine in some points ,i'll build one to see the diference...
last point, i build those for my personal pleasure and sometimes for very closed friends...
here is a link on one of mines:  https://www.youtube.com/watch?v=lvAB_gq7inw
Peace&diy

rigsmith, you're simply ridiculous.
You act like you own NJD siren secrets and things but this is not.
Be respectful even with China. Yes if China will copy will not be a tragedy.
You think you are the best and this is fair. But be respectful with others.
You clone, We clone, They clone.

Just like yourself Rastan I decided to sign up for this forum and comment only on this thread because I was a bit emotional. Someone was telling me this on Facebook winding me up while lots of other stuff was going on in our lifes. Sorry. 

We wish to Remove all our comments but its not possible. 

This thread is from 2015 and people want to keep bringing it back to attention. 

As Professional engineers we rarely get personally involved, Sorry for coming here and airing views. Big mistake.

Copy copying copied. Copy my bins. Copy my amp. Copy my pre. Copy my tops.

Where the hell is an original sound system now??????

Copy me flippin valve amp.

Listen to my riddim. Copy that too. Lots of people with no imagination. Go to a dance and feel ire. Don't have any respect for someone elses originality, just copy up dem style.

And then feel empty. Buddhists call it "hungry ghost realm"
