Low-pass dirt filter

This week I boxed up the filter I’ve been working on in this custom made case (thanks Ponoko). I’m really happy with it, it sounds good and now it looks good too. Sound samples to come – it sounds great with guitar as well as your typical synthy application.

Update: I’ve just sold this one so get in touch if you’d like me to build you another.

Update: I’ve used this project as an example for a tutorial I wrote on the Ponoko forum
