3. Setup and Installation
The EMG ACS BAJO pickup is designed for straightforward installation into the soundhole of compatible acoustic guitars. Professional installation is recommended if you are unfamiliar with guitar electronics or modifications.
3.1 Compatibility
- Compatible with: Steel string acoustic guitars (6-string and 12-string).
- Not compatible with: Nylon string guitars.
3.2 Installation Steps
- Prepare the Guitar: Ensure your guitar is clean and free of debris around the soundhole area. Loosen or remove strings for easier access if necessary.
- Install the Pickup: Gently position the EMG ACS BAJO pickup into the soundhole. The pickup is typically secured by adjustable clamps or screws that grip the edges of the soundhole. Ensure it is centered and stable.
- Install the Endpin Jack: The pickup comes with a prewired endpin jack. This usually requires enlarging the existing endpin hole on your guitar to accommodate the jack. Carefully route the pickup wire to the endpin hole and secure the jack.
- Connect Power: The active preamp requires power. The system includes batteries. Install the batteries into the designated battery compartment, typically located near the endpin jack or within the pickup assembly itself. Ensure correct polarity.
- Test Connection: Once installed, plug your guitar into an amplifier or PA system. Test the pickup's functionality and adjust the volume control.
For detailed diagrams and specific instructions, refer to the manufacturer's official installation guide, often available on the EMG website.
4. Operating Instructions
Operating the EMG ACS BAJO pickup is straightforward once installed.
- Connect to Amplifier: Plug a standard 1/4-inch instrument cable into the endpin jack of your guitar. Connect the other end to your amplifier, mixer, or audio interface.
- Power On: The active preamp automatically powers on when a cable is inserted into the endpin jack.
- Adjust Volume: Use the integrated volume control on the pickup to adjust the output level. Start with a lower volume setting on your amplifier and gradually increase it to your desired level.
- Disconnect: To conserve battery life, always unplug the instrument cable from the endpin jack when not in use.
5. Maintenance
5.1 Cleaning
Wipe the pickup surface with a soft, dry cloth to remove dust and fingerprints. Avoid using abrasive cleaners or solvents, as these can damage the finish.
