Having assembled the Proto Pedal in the Proto Pedal Assembly Guide, we’d like to continue by actually building an effect circuit on the board. The circuit we’ll be basing this on is Fred Forssell’s swinging-input equalizer.

Required Materials

To build the EQ circuit, we’ll need to following components:


You’ll also need the usual tools to solder things together.

Additionally, while it’s not required, we were using a Resistor Lead Forming tool to get the resistors bent to precise lengths.
