4. Setup and Installation
Installation of the EMG M-80 pickup requires basic soldering skills and familiarity with guitar electronics. If you are unsure about any step, it is recommended to seek assistance from a qualified guitar technician.
4.1 Pre-Installation Considerations
- Ensure the pickup is compatible with your guitar's bridge spacing. The M-80 is designed for Gibson Tune-o-matic bridge width, with a maximum string width of 2 inches (51mm).
- Gather necessary tools: soldering iron, solder, wire cutters, screwdrivers, multimeter (optional).
4.2 Wiring Instructions
- Remove Existing Pickup: Carefully desolder and remove your guitar's existing pickup and associated wiring.
- Install M-80 Pickup: Mount the M-80 pickup into the guitar's cavity using the provided screws and springs. Adjust height as desired.
- Connect Potentiometers: Use the quick-connect cables to link the M-80 pickup to the volume and tone potentiometers.
- Connect Output Jack: Wire the stereo output jack according to the provided EMG wiring diagram. The stereo jack is crucial for switching the 9V battery on/off when a cable is inserted/removed.
- Connect Battery: Attach the 9-Volt battery clip to a fresh 9V battery and connect it to the wiring harness. Ensure the battery is securely placed in the guitar's control cavity or a dedicated battery compartment.
- No String Grounding: The EMG M-80 is an active pickup and does not require string grounding. Do not connect any ground wires to the bridge or strings.
- Test Functionality: Before reassembling your guitar, plug it into an amplifier and test the pickup's functionality, including volume and tone controls.
For detailed wiring diagrams and specific configurations (e.g., multiple pickups, different control layouts), please refer to the official EMG website or the wiring diagrams included with your product packaging.
5. Operating the M-80 Pickup
The EMG M-80 operates like any standard guitar pickup, but its active design offers distinct advantages:
- Consistent Output: The low-impedance output ensures that your tone remains consistent regardless of cable length or the use of wireless systems.
- Volume and Tone Controls: Utilize your guitar's volume and tone potentiometers to shape your sound. The active circuitry provides a wider range of usable tones without significant signal loss.
- Battery Power: The M-80 requires a 9-Volt battery for operation. The battery is only engaged when a guitar cable is plugged into the stereo output jack. Always unplug your guitar when not in use to conserve battery life.
6. Maintenance
Proper maintenance will ensure the longevity and optimal performance of your EMG M-80 pickup.
- Cleaning: Wipe the pickup cover and surrounding areas with a soft, dry cloth to remove dust and grime. Avoid using abrasive cleaners or solvents.
- Battery Replacement: Replace the 9-Volt battery regularly, or as soon as you notice a decrease in output or clarity. A typical 9V alkaline battery can last for hundreds of hours of playing time, but this varies based on usage and the number of active pickups.
- Connections: Periodically check all quick-connect and soldered connections to ensure they are secure. Loose connections can lead to intermittent signal or noise.
7. Troubleshooting
If you encounter issues with your M-80 pickup, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound or very weak sound | Dead or low battery Loose connection Faulty cable/amp | Replace 9V battery Check all quick-connects and soldered joints Test with a different cable and amplifier |
| Excessive hum or noise | Improper grounding (if attempted) Interference from external sources Faulty wiring | Ensure no string grounding is present Move away from power sources or fluorescent lights Re-check all wiring connections |
| Volume or tone controls not working | Faulty potentiometer Incorrect wiring | Test or replace potentiometer Verify wiring against EMG diagrams |
If these steps do not resolve the issue, contact EMG customer support or a qualified guitar technician.
