C-904B Voltage Controlled High Pass Filter
The Club Of The Knobs C-904B is a voltage-controlled high-pass filter that adds a whole new dimension to your guitar's sound. Unlike a standard passive high-pass, this pedal puts you in the driver's seat, allowing you to sculpt your tone with surgical precision. At its core, the C-904B is a state-variable filter that lets you sweep the cutoff frequency from a deep, rumbling 20Hz all the way up to a sparkling 2kHz. But this is no ordinary filter - it's voltage-controlled, meaning you can modulate that cutoff in real-time using an expression pedal or other control voltage source. Suddenly, your guitar becomes a dynamic, breathing entity, with the filter sweeping and oscillating to create mesmerizing textures. Pair the C-904B with fuzz, overdrive, or even synth-like tones, and you'll unlock a whole new world of sonic possibilities. Crank the resonance for searing, resonant peaks, or dial it back for a more subtle high-end sheen. Either way, this pedal injects your sound with an unmistakable sense of movement and life. While the C-904B may not have the name recognition of some boutique pedals, its unique voltage-controlled design has made it a secret weapon for in-the-know guitarists. If you're after something to breathe new life into your rig and inspire your playing, the C-904B is well worth a closer look.
