Mod Extravaganza - Tweaking The Filtering

Lesson Overview: Tweaking The Filtering

This is the lesson where the Big Muff’s low end gets a makeover—and your ears take the wheel.

We’ve built the basic circuit, but now it’s time to shape its voice. In this session, we experiment with different capacitor values to tweak the frequency response, with a focus on the coupling caps that govern low-end behavior.

In this lesson, you’ll learn:

• How different capacitor values alter the Big Muff’s tone and feel.
• What happens when you push capacitor values to the extreme—and how that reshapes the lows, saturation, and playing dynamics.
• How filtering choices affect the dynamic feel of your playing.
• The sonic differences between vintage-leaning configurations and more modern voicings.

We’ll walk through key cap-swaps in real-time, hear the results, and unpack what’s actually happening to the signal. By the end, you’ll not only know how to tweak the tone—you’ll have a gut-level feel for what each change means in musical terms.
