Professor’s Notes
The Blurst turns your guitar or bass into a swirling, animated filter machine—think auto-wah meets synth pulse, but with a wild streak. It’s expressive, musical chaos on command, perfect for players who like their tone to move. Dial it in slow for liquid sweeps or fast for funky stutters—either way, it’ll slice straight through the mix with character to spare.

Description
The Electro-Harmonix Blurst is a modulation filter that adds rhythmic, envelope-style movement to your tone—without relying on your picking dynamics. Instead, the filter is driven by a built-in LFO, giving you full control over rate, range, resonance, and waveform. The result is everything from slow, ambient sweeps to rapid, synth-like filter effects that transform your instrument into a living, breathing signal.

With an expression pedal input and tap tempo capability, you can shape and time your modulation precisely to your playing. The Blurst works beautifully on guitar, bass, or synth, making it a versatile creative tool for players chasing new textures and motion in their tone.
