Session 3: Breadboarding the Op-Amp

## Session 3: Breadboarding the Op-Amp If the transistor is the building block of analog electronics, the **op-amp** is the Swiss Army knife. Op-amps show up everywhere in guitar pedals — as clean boosts, buffers, tone stacks, and the gain stages at the heart of overdrive circuits. The Tube Screamer, the RAT, the LM308-based fuzz variants — all built around op-amps. In this session we'll get hands-on with the op-amp on a breadboard and learn how to put it to work. We'll cover: * **What an op-amp is** — and how it differs from a transistor amplifier * **Biasing** — setting up the op-amp to work with a single-supply voltage, like a 9V battery * **Setting the gain** — using feedback resistors to dial in exactly how much amplification you want * **Building a boost or buffer circuit** — and hearing the difference it makes No prior experience with op-amps needed. If you've been following the series, you already have all the foundation you need — but newcomers are welcome too. Already working on a pedal project? Bring it! Whether you have questions, need a second pair of eyes, or just want to solder alongside others, you're welcome to work on your own build.
