Electro-Harmonix Blurst! Modulated Filter Pedal

What is the Electro-Harmonix Blurst Modulated Filter Pedal?
The Electro-Harmonix Blurst Modulated Filter Pedal is a dynamic and creative tool that brings synth-style modulation and lowpass filtering to your pedalboard. This pedal is designed for musicians who want to explore new sonic territory, offering dramatic frequency sweeps, resonant peaks, and a wide range of modulation effects. Whether you play guitar, bass, or even keyboards, the Blurst provides a versatile and fun way to add depth, movement, and excitement to your sound. With its intuitive controls and ability to sync with the tempo of your music, this pedal allows you to craft intricate, rhythm-driven effects or chaotic, free-flowing sweeps.

Control Your Sound with LFO Modulation
At the heart of the Blurst is an LFO (low-frequency oscillator) that modulates the cutoff point of the variable-resonance lowpass filter. This allows you to create sweeping frequency movements, from subtle, slow shifts to rapid, intense oscillations. The Range knob lets you dial in the frequency sweep range, while the Rate knob controls the speed of the modulation. For precise synchronization with your music, the Tap footswitch allows you to match the LFO speed to the beat of your track. Whether you prefer a smooth sweep or something more aggressive, the Blurst provides endless possibilities to shape your sound in real time.

Add Dimension with Expression Pedal Control
For even more control, the Blurst supports an expression pedal (sold separately), adding an additional layer of expression to your filter effects. The expression pedal allows you to directly manipulate key parameters such as Range, Rate, and Filter frequency on the fly, providing full control over your sound. This feature enables you to craft more complex effects, like phaser-style sweeping, rotary-style ramp-ups, or even manual filter sweeps similar to a wah pedal. By adjusting these parameters live, you can inject creativity and spontaneity into your performance, making the Blurst an invaluable tool for dynamic, responsive playing.

Shape Your Tone with Resonance and Blend Control
The Blurst features a Resonance control that boosts frequencies around the filter cutoff, adding a harmonic edge to the sweep. You can choose to keep the resonance subtle for a smooth, more balanced effect or crank it up for dramatic, stab-like tones that cut through your mix. The Blend knob gives you control over how much of the filtered signal is mixed into your original tone, allowing you to preserve the integrity of your sound while still adding the sweep effect. This feature ensures that the Blurst remains a flexible tool, letting you tailor the intensity of the filter sweep to suit your playing style.

Sync Your Modulation with Tap Divide and Shape Controls
The Blurst offers Tap Divide settings, which allow you to subdivide the LFO rate within the tempo you’ve set with the Tap footswitch. This is ideal for musicians who want to create more intricate, rhythmically complex effects. Additionally, the Shape mini toggle lets you adjust the waveform of the sweep, choosing from back-and-forth, upward, or downward motion. These features combine to give you a highly customizable modulation experience, whether you’re looking to add subtle movement to your sound or experiment with extreme, rhythmic sweeps.

Versatile for Guitar, Bass, Keyboards, and More
While the Electro-Harmonix Blurst Modulated Filter Pedal is a standout choice for guitarists looking for innovative filter effects, it’s also a powerful tool for bass players and keyboardists. The ability to create sweeping modulations on bass, for example, opens up a whole new world of sonic possibilities, from funky, rhythmic swells to smooth, controlled filter sweeps. For keyboardists, the Blurst integrates perfectly with Electro-Harmonix’s keyboard emulation pedals or POG models, enhancing your sound with rich, evolving filter modulation. This versatility makes the Blurst an essential addition to any musician's pedalboard, regardless of instrument.
