Tim Escobedo’s [Bronx Cheer](https://music-electronics-forum.com/filedata/fetch?id=870776&d=1468336196) (an “envelope waveshaper filter”), essentially a transistor fuzz with a filter attached to it. The resonant fuzz filter frequency changes when one hits the notes harder, and changes again as the notes decay. The build includes a small transformer/inductor intended to mimick the impedance of a guitar pickup.

You can find the build notes and stripboard layout in the [verified layouts thread](https://lookmumnocomputer.discourse.group/t/verified-stripboard-layouts/81/542).
