Proto Pedal Example: Analog Equalizer Project
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.
Two-band equalizer pedal.
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.
- If you’re here, we’ll assume that you’re familiar with the Proto Pedal Assembly and Theory guide. If not, you should start there.
- In parallel with this guide, you might also be interested in some information abouyt preparing the Proto Pedal chassis.
- This project is based on Fred Forssell’s Equalizer Whitepaper, in particular his Equal Resistor Gyrator.
