Operating Instructions
The VOX V847-A Wah Pedal is designed for intuitive operation. Here's how to use it:
- Engaging the Effect: To turn the wah effect ON, press down firmly on the toe end of the pedal until you hear a click. This activates the internal switch.
- Disengaging the Effect: To turn the wah effect OFF, press down firmly on the toe end of the pedal again until you hear a click. The pedal will then be in bypass mode, allowing your guitar's dry signal to pass through.
- Controlling the Wah Effect: Once engaged, rock the pedal back and forth with your foot to sweep through the wah effect's frequency range.
- Heel-Down Position: Pushing the pedal all the way back (heel-down) emphasizes lower frequencies, creating a deep, resonant tone.
- Toe-Down Position: Pushing the pedal all the way forward (toe-down) emphasizes higher frequencies, producing a sharp, cutting tone.
- Experimentation: Experiment with different rocking speeds and ranges to achieve various expressive sounds, from subtle vocal-like sweeps to dramatic, percussive effects.
Maintenance
Proper maintenance will ensure the longevity and optimal performance of your VOX V847-A Wah Pedal:
- Cleaning: Wipe the pedal with a soft, dry cloth to remove dust and grime. Avoid using abrasive cleaners or solvents, as they may damage the finish.
- Storage: When not in use for extended periods, store the pedal in a cool, dry place away from direct sunlight and extreme temperatures. If using battery power, remove the battery to prevent leakage.
- Connections: Periodically check all cable connections to ensure they are secure and free from damage. Loose connections can lead to signal loss or noise.
