Setup
Before using your Behringer HELLBABE HB01 pedal, ensure proper connection and power supply.
- Power Supply: The pedal can be powered by a 9V battery or an optional 9V DC power adapter (not included).
- To install a battery, open the battery compartment located on the underside of the pedal. Connect a 9V battery to the clip and place it inside the compartment.
- For external power, connect a 9V DC power adapter to the DC input jack.
- Connections:
- Connect your guitar to the "IN" jack of the HB01 pedal using a standard 1/4-inch instrument cable.
- Connect the "OUT" jack of the HB01 pedal to your amplifier or other effects pedals using another 1/4-inch instrument cable.
- Placement: Place the pedal on a stable surface or integrate it into your pedalboard.
Operating Instructions
The HELLBABE HB01 offers intuitive controls for shaping your wah sound.
Controls:
- LEVEL: Adjusts the overall output volume of the wah effect.
- RANGE: Controls the heel-down frequency range of the wah. Turning this knob allows you to set the lowest frequency the wah pedal reaches, from 440 Hz down to 250 Hz.
- Q: Adjusts the sharpness or intensity of the wah effect. Higher Q settings result in a more pronounced, vocal-like wah.
- BOOST: Activates and controls the built-in boost function. This can be used to increase the signal level for solos or to drive your amplifier harder.
- MODE Switch: Selects between different wah modes (e.g., classic wah, filter, etc.). Refer to the detailed specifications for specific mode functionalities.
Usage:
- Engaging the Wah: Press down on the pedal to engage the wah effect. The optical sensor detects your foot movement.
- Wah Sweep: Move your foot back and forth on the pedal to sweep through the frequency range, creating the characteristic wah sound.
- Adjusting Resistance: The spring-back mechanism's resistance can be adjusted to suit your playing style. Consult the pedal's underside or side panels for adjustment screws, if available.
- Using the Boost: Engage the BOOST function as needed to add volume or drive to your signal. Adjust the BOOST knob to control the level of the boost.
