Electro Harmonix Blurst

EHX has grafted technology found in keyboard and modular synthesizers into a pedal designed for guitarists and bass players. The Blurst modulates sound like an envelope filter controlled by an internal oscillator. – Features an analog low pass filter with adjustable resonance
– Three modulation waveform shapes: triangle, rising saw-tooth and falling saw-tooth
– Modulation rate is set by either the rate knob or a combination of the tap footswitch and tap divide toggle switch offering quarter, dotted eighth and triplet rhythms
– Three EXP modes, range, rate and filter, can be controlled by an expression pedal or control voltage source like EHX’s 8 Step Program Analog Expression/CV Sequencer
– Range knob sets the frequency range of the filter’s modulation, Blend control adjusts the dry/filtered signal mix
