Schwurbel

From the vendor

This is pretty fucking intense! This fucker will turn your fancy ass signal into something like a squarewave. Then you can set the pulsewidth of said squarewave. And if you are completely bonkers (wich you probably are) you can even modulate the pulswidth. Probably not for your Clapton coverband and maybe not even for anything else but it is sooo much fucking fun!!!!!! There are build docs to build this with or without the modulation part so if you just want a fucking nasty fuzz/distortion with two pots then you can still do that. If you wonder why I am swearing so much right here you shoud get the PCB and fucking find out yourself. Sorry if that was rude. I didn't mean to be rude.

V2 of this PCB has the option to switch the modulation on and off Pretty cool huh?
