Some videos of the dubsiren i been working on. This was the first batch model, and still available.

My intention after researching all the models out there ( NJD, SE10, etc) was to build one that was the most versatile. So i ended with this model where instead of presets style( through a rotary switch), went with the free form style of dubsiren as it makes all the sounds the others do and many more.
PS- contact me if you want to know more details or even order one. !
