Scream Filter (work in progress)

It's been a while... I was very busy but I still gather a lot of ideas and try to finish some pieces...
Here's one of them :

Still experimental, here’s the Screaming Filter… not finished yet, I have to add a few things and finish the enclosure (painting ...). The front panel’s artwork is taken from Munch’s famous painting called “Skrik”, I really like this painting and it fits very well with the “scream theme”.  I added a low-resolution + black and white effect.
The enclosure is originally designed for a power supply, the shape of the box is pretty cool but there's not much room and it was quite hard to put the PCB + the batteries in it.
Front view : 2 potentiometers controlling the amount of "screaming effect" and distortion, 5 switches (5 steps of audio destruction)
Rear view : 6.35mm input and output jack, 1 switch
I like the incurved shape of the knobs, it gives a vintage touch...

Sorry, there's no video for the moment... work in progress !
