2. Setup
Follow these steps to set up your Twiggy Blues pedal:
- Power Connection: Connect a standard 9V DC power adapter (center negative) to the "DC 9V" input jack on the pedal. Ensure the power source provides stable and clean power to prevent noise.
- Instrument Input: Connect your guitar to the "IN" jack on the right side of the pedal using a standard 1/4-inch instrument cable.
- Output Connection: Connect the "OUT" jack on the left side of the pedal to your amplifier's input or an audio interface/mixer using a standard 1/4-inch instrument cable.
- Cabinet Simulation: If connecting directly to a PA system, mixer, or audio interface, ensure the "CABINET SIM" switch is set to "ON". If connecting to a guitar amplifier, set the switch to "OFF" to bypass the cabinet simulation.

3.2. Effect Modules

Image 3.2: Overview of the four integrated effects.
3.2.1. Compressor (COMP)
The Compressor module provides a smooth and sustained tone. Use the footswitch to engage or bypass the effect.
- VOL: Adjusts the overall output volume of the compressor.
- COMP: Controls the amount of compression applied to the signal. Higher settings result in more sustain and a more even dynamic range.
3.2.2. Overdrive (BLUES)
The BLUES module simulates a vintage Dumble-style tube amplifier, offering a range of overdrive tones suitable for blues and classic rock. Engage with its dedicated footswitch.
- VOL: Sets the output volume of the overdrive effect.
- TONE: Adjusts the tonal character, from darker to brighter.
- GAIN: Controls the amount of distortion or saturation. Lower settings provide a subtle breakup, while higher settings yield more aggressive overdrive.
3.2.3. Delay (SLAPBACK)
The SLAPBACK module provides an analog-voiced delay effect, ideal for adding depth and rhythmic repeats. Activate using its footswitch.
- BLEND: Controls the mix between the dry signal and the delayed signal.
- REPEAT: Adjusts the number of delay repeats.
- TIME: Sets the delay time, from short slapback echoes to longer repeats (up to 500ms).
3.2.4. Reverb (AIR)
The AIR module offers a high-quality reverb effect to add spaciousness to your sound. Engage with its footswitch.
- MIX: Controls the amount of reverb mixed with the dry signal.
3.3. Cabinet Simulation
The built-in cabinet simulation allows for direct connection to a PA system, mixer, or audio interface, providing a guitar cabinet-like sound without needing an amplifier. Use the toggle switch to activate or deactivate this feature.

3.4. LED Indicators
Each effect module features LED indicators around its control knobs. These LEDs illuminate when the corresponding effect is active, providing clear visual feedback on the pedal's status during use.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Twiggy Blues pedal.
- Cleaning: Use a soft, dry cloth to clean the pedal's surface. Avoid abrasive cleaners or solvents, which can damage the finish or internal components.
- Storage: Store the pedal in a dry environment, away from extreme temperatures, humidity, and direct sunlight. When not in use for extended periods, disconnect the power adapter.
- Connections: Periodically check all cable connections for wear and tear. Ensure jacks are free of dust and debris.
5. Troubleshooting
If you encounter issues with your Twiggy Blues pedal, refer to the following common troubleshooting steps:
- No Sound:
- Ensure all cables (input, output, power) are securely connected.
- Verify the power adapter is functioning correctly and providing 9V DC (center negative).
- Check if your guitar and amplifier are working independently.
- Ensure the volume knobs on the pedal and your amplifier are not set to zero.
- Unwanted Noise/Hum:
- Use a high-quality, regulated 9V DC power supply specifically designed for guitar pedals.
- Ensure all cables are shielded and in good condition.
- Try isolating the pedal from other electronic devices that might cause interference.
- Effect Not Engaging:
- Press the footswitch firmly to ensure it engages. The LED indicator should light up.
- Check the knob settings for the specific effect; some effects may be subtle at low settings.
If problems persist, contact SONICAKE customer support for further assistance.
