This is an officially licensed reissue of the original Synthasystem filter. I haven't altered the design one bit so it's as nasal, screamy, twitchy and wonderful as the original.

To keep the packaging compact we've done most of the passives on the board in SMT, but for the DIY builders the diodes, transistors, and important capacitors are all through-hole so you can experiment with and use whatever you like.

Many thanks to Nyle Steiner and David Ingebretsen for their permission and support of this project, and to Dakota Melin for his fantastic work on the PCBs. (For those of you who care about this sort of thing, all three of those guys make a little bit of money every time one of these things sells.)
