Description
Unleash the raw power of vintage British amps with the Catalinbread Dirty Little Secret. Designed for guitarists who crave the classic-era Marshall sound, this pedal delivers an authentic rock experience right at your feet. With its two distinct circuits—the Super Lead and Super Bass—this pedal offers a dynamic range that channels everything from the iconic plexi tones to the roaring JCM800, all while maintaining exceptional touch sensitivity.
The Dirty Little Secret isn't just a pedal; it's the backbone of your rig. Its versatility allows it to be an "always on" overdrive, perfectly complementing other effects in your pedalboard. Whether you're looking to drive your tone into gritty overdrive or pull back for a cleaner, more nuanced sound, this pedal's intuitive controls give you the flexibility you need. Simply adjust the master, treble, middle, bass, and preamp dials to craft your perfect tone.
Flip the internal slider switch to toggle between the two modes. The Super Lead mode offers a high-gain, mid-focused punch, while the Super Bass mode provides a warmer, low-mid emphasis, perfect for pairing with fuzz pedals. This pedal's adaptability makes it a must-have for musicians looking to explore a wide array of sonic possibilities without sacrificing the quality or character of their sound.
Key Features:
- Two circuits in one: Super Lead and Super Bass
- Controls: Master, Treble, Middle, Bass, Preamp
- Internal slider switch for circuit selection
- True-to-amp response ideal for stacking with other pedals
- Compact design, pedalboard friendly
