The Electro-Harmonix Blurst Modulated Filter unleashes a universe of filter-based sounds for adventurous guitarists and bassists. This powerful pedal takes its inspiration from modular synthesizers, offering an analog low-pass filter with adjustable resonance for shaping your core tone.

Unleash the Blurst's true power with its internal oscillator, modulating the filter cutoff for effects ranging from funky envelope filter-like sweeps to pulsating synth patterns. Choose from triangle, rising sawtooth, or falling sawtooth waveforms, then dial in the perfect speed with the rate knob or tap tempo footswitch. An expression input offers even more real-time control.

Key Features:

• Analog low-pass filter with adjustable resonance
• Three modulation waveform shapes
• Tap tempo with rhythmic subdivisions
• Expression pedal control over range, rate, and filter
