1. Overview
The MOOER Acoustikar is a compact acoustic guitar simulator pedal designed to transform the sound of an electric guitar into that of an acoustic guitar. It offers three distinct modes: Piezo, Standard, and Jumbo, allowing for a versatile range of acoustic tones. This pedal is built with a full metal shell, ensuring durability and longevity.

2.1 Power Supply
The Acoustikar pedal requires a 9V DC regulated AC adapter for power. Ensure the adapter has a plug polarity where the positive is on the barrel and the negative is in the center.
2.2 Connections
- Connect your electric guitar to the INPUT jack (1/4" mono audio jack) on the right side of the pedal.
- Connect the OUTPUT jack (1/4" mono audio jack) on the left side of the pedal to your amplifier or next effect pedal.
- Plug the 9V DC power adapter into the DC IN power jack.

3. Operating Instructions
3.1 Controls

3.2 Mode Switch
The 3-way toggle switch allows you to select between three different acoustic simulation modes:
- Piezo Mode: Simulates the sound from a piezo pickup installed on an electric-acoustic guitar, offering a bright and articulate tone.
- Standard Mode: Simulates a normal acoustic guitar sound, providing a balanced and natural acoustic tone.
- Jumbo Mode: Simulates a bigger body acoustic guitar with more low end and resonance, ideal for a fuller, richer sound.

- Verify that the power adapter is correctly connected and providing the correct voltage (9V DC).
- Ensure the footswitch LED is illuminated, indicating the effect is active. If not, press the footswitch.
- Test with different cables or a different power supply to rule out faulty accessories.
5.2 Undesired Sound / Tone Issues
- Adjust the LEVEL, BODY, and TOP knobs to fine-tune the acoustic tone.
