Introdución
The Electro-Harmonix Blurst! is a modulated filter pedal designed for guitarists and bass players. It integrates technology from keyboard and modular synthesizers to create dynamic filter effects. Unlike traditional envelope filters, the Blurst!'s filter response is controlled by an internal oscillator, offering unique sonic exploration.

Configuración
Follow these steps to properly set up your Blurst! pedal:
- Conexión de alimentación: Connect a 9V DC power adapter (center positive) to the 9V power jack on the top of the pedal. The Blurst! requires a 9V battery or a 9V DC power supply.
- Conexión de entrada: Conecta o teu instrumento (guitarra, baixo, etc.) ao ENTRADA conector jack situado no lado dereito do pedal usando un cable de instrumento estándar de 1/4 de polgada.
- Conexión de saída: Conecta o SAÍDA toma no lado esquerdo do pedal para o teu amplifier or the next effect pedal in your signal chain using a standard 1/4-inch instrument cable.
- Expression Pedal (Optional): For external control, connect an expression pedal or a Control Voltage (CV) source (such as the EHX 8 Step Program Analog Expression/CV Sequencer) to the EXP jack on the left side of the pedal.

Instrucións de funcionamento
The Blurst! pedal features several controls to shape your modulated filter sound:
Controis:
- Botón VOL: Controla o volume de saída xeral do pedal.
- Botón BLEND: Adjusts the mix between your dry (unaffected) signal and the wet (filtered) signal. Turn clockwise for more filtered sound, counter-clockwise for more dry signal.
- RESONANCE Knob: Controls the Q or peak of the filter. Higher settings create a more pronounced, resonant filter sweep.
- Botón de VELOCIDADE: Sets the speed of the filter modulation. This can also be controlled by the TAP footswitch.
- RANGE Knob: Determines the frequency range over which the filter modulates. Turn clockwise for a wider sweep, counter-clockwise for a narrower sweep.
Interruptores de palanca:
- EXP MODE Switch: Selects the parameter controlled by an external expression pedal or CV source.
- GAMA: Expression pedal controls the filter's frequency range.
- TARIFA: Expression pedal controls the modulation rate.
- FILTRO: Expression pedal controls the filter's center frequency.
- TAP DIVIDE Switch: When using the TAP footswitch to set the modulation rate, this switch divides the tapped tempo into different rhythmic values.
- Quarter Note: Modulation rate matches the tapped tempo.
- Dotted Eighth Note: Modulation rate is a dotted eighth note of the tapped tempo.
- Triplet: Modulation rate is a triplet of the tapped tempo.
- SHAPE Switch: Selects the waveform shape of the internal oscillator that modulates the filter.
- Triángulo: Smooth, symmetrical modulation.
- Rising Saw-tooth: Rapid rise, slow fall modulation.
- Falling Saw-tooth: Slow rise, rapid fall modulation.
Pedales:
- Pedal TAP: Tap this footswitch two or more times to set the modulation rate. The rate will synchronize to your tapped tempo, adjusted by the TAP DIVIDE switch.
- Pedal de derivación: Toggles the effect on and off. When the effect is on, the LED indicator will illuminate.

Mantemento
To ensure the longevity and optimal performance of your Blurst! pedal:
- Limpeza: Usa un pano suave e seco para limpar o exterior do pedal. Evita produtos de limpeza abrasivos ou solventes.
- Almacenamento: Garda o pedal nun lugar fresco e seco, lonxe da luz solar directa e de temperaturas extremas.
- Substitución da batería: If using a 9V battery, replace it when the LED indicator dims or the pedal's performance degrades. To replace, remove the four screws on the bottom plate and carefully lift the plate. Disconnect the old battery and connect a new 9V battery, then reattach the bottom plate.
- Conexións: Comprobe periodicamente todas as conexións dos cables para detectar desgaste. Asegúrese de que os conectores estean libres de po e residuos.
Resolución de problemas
If you encounter issues with your Blurst! pedal, consider the following:
- Sen son:
- Ensure all cables are securely connected to the input, output, and power jacks.
- Verify the power supply is functioning correctly and providing 9V DC (center positive).
- If using a battery, check if it needs replacement.
- Proba con diferentes cables e un amplifier/instrument to isolate the problem.
- Son débil ou distorsionado:
- Comproba o VOL e MESTURA knob settings.
- Ensure your instrument's output level is appropriate for the pedal's input.
- If using a battery, replace it.
- Modulation Not Working:
- Comproba o TARIFA knob setting.
- If using the TAP footswitch, ensure you are tapping it consistently and the TAP DIVIDE switch is set as desired.
- Verifica o FORMA switch is set to a desired waveform.
- Expression Pedal Not Responding:
- Ensure the expression pedal is correctly connected to the EXP jack.
- Verifica o MODO EXP switch is set to the desired parameter (RANGE, RATE, or FILTER).
- Confirm the expression pedal is compatible and functioning correctly.
