Super Simple DIY Resonant Low Pass Filter Circuit

Hey, So here is my newest project. It’s a simple low-pass filter with 4 frequency ranges, and it uses just one transistor and a few small parts. The design is by Hilltree, and I haven’t changed much on his design other than replacing a few values here and there where I didn’t have his values. It’s a really easy project and would be great for a mod on an existing effect or synth. This project would be great for beginners. Anyway enjoy! Oh and please check out the final build here: .
