Picked up a d.i.y kit from 'Synthrotec' The clone of the original DS8 Analogue drum synth.....PICS...
It's like the DS7 but added extras !....Check here... http://www.synthrotek.com/store/-c-32.h ... 47d5133f07
Also worth a look is...http://m.bareille.free.fr/ds7clone/ds8.htm
This is actually not a dub siren at all, no more than the ds7 is but is more than capable of producing warm analogue noises for dubbing it up.
Sounds great through a delay as you would expect.
Happee Daze !
