The ES2 utilizes three uniquely positioned, individually calibrated pickup sensors located behind the saddle. The individual pickup pressures are factory set and will likely only need to be adjusted if the saddle is being removed or replaced. Pressure on each sensor is controlled by turning the adjustment screws (visible behind the saddle; see photo below). The small, visible circles behind the bridge contain tiny adjustable arms. The small adjustment screws on top move the arms forward and backward, increasing and decreasing the pressure of the pickup sensors against the lower rear portion of the saddle, similar to pushing on a brake pedal in a car.
Note: The saddle should not be removed or replaced without first loosening the adjustment screws located on the top of the pickup housings. Otherwise the pickup could be damaged.
To remove the saddle: The pickup sensors must first be loosened (backed away from the saddle) by loosening the pressure adjustment screws located on top of the housings behind the saddle. The adjustment will require a .050 hex key (Allen wrench).
Turning the hex key counterclockwise 1-½ turns will back the sensor arms away from the saddle so it can be removed from the slot easily. Once the saddle is placed back in the slot, the pickup sensors can be reset with the saddle by turning them clockwise 1-½ turns.
Fine Adjustment
Very light pressure on the sensors is all that is needed to make the system work well. Changing the tension on the sensors will change the timbre of the sound and volume of the pickup slightly. Approximately one full turn of the tension screw is the maximum amount of pressure variance.
We suggest that any adjustments for sound be made using the following process:
1) Plug the guitar in and turn the volume up.
2) While plucking sets of two strings at a time, turn the adjustment screw associated with those strings (E/A - D/G - B/E) one turn counterclockwise until the sound of those strings diminishes. This will loosen the pressure on the sensor.
3) To engage the pickup for those strings, turn the screw back again clockwise ¼ turn at a time while plucking the strings until the sound of the strings returns. This will increase the pressure on the sensors. Repeat the process for the other string pairings (D/G - B/E).
Additional Note: The pickup system is held in place in the guitar by the pressure of the sensors against the saddle. If the pickup is accidently pushed out during saddle replacement, it can easily be put back into the bridge by pushing it up through the three pickup holes. The top of the pickup housing should be flush with the top of the bridge to be accurate.
