Blurst Modulated Filter

The Electro-Harmonix Blurst Modulated Filter pedal features an analog low pass filter with adjustable resonance. It offers three modulation waveform shapes: triangle, rising saw-tooth, and falling saw-tooth. The modulation rate can be 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. The pedal includes three EXP modes (range, rate, and filter) that can be controlled by an expression pedal or a control voltage source like EHX's 8 Step Program Analog Expression/CV Sequencer. The range knob sets the frequency range of the filter's modulation, while the blend control adjusts the dry/filtered signal mix. The pedal operates on a 9.6VDC-200mA power supply, which is included. Its dimensions are 2.75 inches (width) x 4.5 inches (length) x 2.1 inches (height).
