    The EQ that Changed the World – API 550a



    EQ Legend Unplugged: The API 550A Breakdown

    In this week’s episode of Inside the Recording Studio, Chris & Jody twist the knobs and roll back the decades for a deep dive into one of the most iconic EQs in pro audio: the API 550A. Whether you’ve seen it on a vintage console or recreated in your favorite plugin, the 550A is a classic that helped define the sound of records for decades—and it’s still going strong today.

    You’ll get a guided tour through the history of the 550A, from its invention at Automated Processes Inc. to who bought the first units. But we’re not stopping there. Chris & Jody unpack the inner workings of the 550A, demystify its EQ bands and frequency points, explain why its proportional Q design matters, and share real-world insights on when and how they use it in the studio.

    Expect a mix of tech savvy, real talk, and some light gearhead banter (plus Friday Finds, of course). If you’re serious about understanding your tools—or just love a good piece of hardware history—this episode is for you.

    Tuesday Tip: Passive vs. Active Pickups


    As opposed to a regular ‘tip’, Chris plays you guitar tracks recorded with either passive or active pickups. Will you be able to pick which is which?

    Which is better, Passive or Active Pickups?



    Passive vs. Active Pickups: What’s Best for Your Tone?

    Guitarists, gather ’round—this one’s for the tone-obsessed, the pedalboard tweakers, and the “don’t-touch-my-pickups” purists. In this electrified episode of Inside the Recording Studio, Chris and Jody spark a lively debate over the long-standing feud: passive pickups vs. active pickups.

    What’s the actual difference between the two? Are you losing nuance with one or missing bite with the other? Whether you’re wielding vintage humbuckers or EMG-powered shredders, Chris and Jody unpack the sonic, technical, and stylistic pros and cons of each design—along with their personal preferences, recording implications, and studio-use tips. You’ll walk away knowing which pickup style fits your tone goals, rig setup, and musical genre.

    Plus: what not to do when you’re done playing (hint: don’t leave your guitar plugged in unless you want a surprise expense), and this week’s Friday Finds drop in with gear to explore.

    Expect laughs, light-hearted jabs, and a few myth-busting moments. Whether you’re building your home studio geararsenal or just wondering why your tone feels flat, this episode will help you pick your pickups wisely.
