The Electro-Harmonix Blurst Modulated Filter is a creative effects pedal that combines modulation effects with a powerful analog filter. Inspired by classic synthesizer "filter sweep" sounds, the Blurst brings these versatile and dynamic effects to guitarists, bassists, and sound designers alike. The pedal features a wide range of capabilities, including an LFO (Low-Frequency Oscillator) with three waveforms (triangle, square, and rising ramp), adjustable resonance, and a variable bypass mode. With built-in expression pedal support, you can have real-time control over parameters like modulation rate, range, or filter sweep. Key Features: Analog Filter: Warm and powerful, perfect for experimental sounds Versatile LFO: Choose from three unique waveforms for a range of modulation textures Expression Pedal Compatibility: Add dynamic control over parameters in real time Wide Applications: Ideal for guitars, bass, synthesizers, and more Whether you’re playing funk, psychedelic rock, electronic music, or something in between, the Blurst offers endless possibilities to transform your sound.
