Product Overview
Image: The EMG ACS BAJO Bandera Acoustic Guitar Sound Hole Pickup, featuring a design inspired by the Mexican flag. This active magnetic pickup is designed to fit into the soundhole of an acoustic guitar.
The EMG ACS BAJO Bandera is an active magnetic soundhole pickup specifically engineered for steel string acoustic guitars (compatible with both 6 and 12-string models). It features a custom-voiced internal preamp for natural phase and frequency response, a built-in volume control, and a prewired endpin jack. Batteries are included for immediate use.
Note: This pickup is not compatible with nylon string guitars.
Setup and Installation
- Prepare Your Guitar: Ensure your acoustic guitar is clean and free of debris around the soundhole area. Loosen the strings to allow access to the soundhole.
- Position the Pickup: Gently slide the EMG ACS BAJO Bandera pickup into the soundhole. The pickup is designed to fit securely within the soundhole. Adjust its position for optimal string balance and aesthetic alignment.
- Secure the Pickup: The pickup typically uses a tension-based mounting system or small screws to secure it within the soundhole. Follow the specific instructions provided in the packaging for your model to ensure it is firmly in place without damaging the guitar's finish.
- Install the Endpin Jack: The pickup comes with a prewired endpin jack. This usually requires drilling a hole in the guitar's end block if one is not already present for a strap button/jack. Professional installation is recommended for this step to avoid damage to your instrument. Connect the pickup's output cable to the endpin jack.
- Install Batteries: The active preamp requires power. Locate the battery compartment (often a small pouch or clip inside the guitar body, accessible through the soundhole) and insert the included batteries, observing correct polarity.
- Test Connection: Once installed, re-string and tune your guitar. Connect the endpin jack to an acoustic amplifier or PA system using a standard instrument cable.
For detailed visual guidance, refer to any installation diagrams or videos provided by EMG.
Operating Instructions
- Power On/Off: The pickup is active when an instrument cable is plugged into the endpin jack. Unplugging the cable will power off the unit and conserve battery life.
- Volume Control: The pickup features a built-in volume control, typically a small knob located on the pickup itself. Rotate clockwise to increase volume and counter-clockwise to decrease volume. Adjust to your desired output level.
- Tone: The custom-voiced preamp is designed to capture the natural acoustic tone. Experiment with your amplifier's EQ settings to further shape your sound.
Maintenance
- Battery Replacement: When the sound becomes weak or distorted, it is likely time to replace the batteries. Always use fresh, high-quality batteries of the specified type. Ensure correct polarity during installation.
- Cleaning: Wipe the pickup gently with a soft, dry cloth to remove dust and grime. Avoid using abrasive cleaners or solvents, as these can damage the finish or electronic components.
- Storage: If storing your guitar for an extended period, unplug the instrument cable from the endpin jack to prevent battery drain.
