Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of your ESP Arming Adjuster. Designed to enhance the tuning stability of guitars equipped with floating tremolos, this device helps prevent unwanted tuning shifts during play and string breakage. Please read this manual thoroughly before installation and use to ensure optimal performance and longevity of your unit.
Product Features
- Innovative Solution: Prevents tuning instability common with floating tremolos.
- Enhanced Tremolo Stability: Semi-locks the tremolo via a counter spring, allowing for arm down and arm up motions without compromising functionality.
- Versatile Compatibility: Suitable for both lock-type and syncro-type tremolos.
- Durable Construction: Made from aluminum with a gold finish.
- Easy to Install: Designed for straightforward integration into your guitar.

Setup and Installation
The ESP Arming Adjuster is designed for installation in the tremolo cavity of your electric guitar. Professional installation is recommended if you are unfamiliar with guitar modifications.
- Prepare the Guitar: Ensure the guitar is unplugged and placed on a stable, padded surface. Remove the tremolo cavity cover from the back of the guitar.
- Identify Mounting Location: The Arming Adjuster is typically mounted between the tremolo block and the body of the guitar, aligning with the tremolo's movement.
- Position the Unit: Place the Arming Adjuster in the tremolo cavity. The plunger end should face the tremolo block, and the spring mechanism should be oriented towards the guitar body.
- Secure with Screw: Use the provided mounting screw to secure the Arming Adjuster to the guitar body. Ensure it is firmly attached but do not overtighten.
- Adjust Tension: The tension of the Arming Adjuster's internal spring can be adjusted to fine-tune its effect on the tremolo. This adjustment is crucial for optimal performance and should be done in conjunction with setting up your guitar's tremolo system.
- Test Functionality: After installation, re-string and tune your guitar. Test the tremolo arm's movement and observe the tuning stability during bends and dives. Adjust the Arming Adjuster's tension as needed to achieve the desired balance between tremolo freedom and tuning stability.

Operating Principles
The ESP Arming Adjuster works by applying a counter-force to the tremolo block, effectively semi-locking it in a neutral position. When a string is bent or breaks, the tension on the tremolo system changes. Without the Arming Adjuster, this change can cause other strings to go out of tune. The Adjuster's spring mechanism absorbs these sudden changes, maintaining the tremolo's position and thus the guitar's tuning.
- Choking Prevention: When bending a string, the Arming Adjuster prevents the tremolo from moving forward, which would cause other strings to go flat.
- String Break Stability: If a string breaks, the sudden loss of tension would normally cause the tremolo to pull back, making all other strings go sharp. The Arming Adjuster counteracts this, keeping the remaining strings in tune.
- Arm Down/Up Functionality: The design allows for full use of the tremolo arm for dives and pulls, as the unit only engages to stabilize the tremolo against unwanted movements.
Maintenance
The ESP Arming Adjuster is a low-maintenance device. Regular inspection is recommended to ensure continued optimal performance.
- Periodic Inspection: Annually, or during string changes, inspect the unit for any signs of wear, corrosion, or damage. Check that the mounting screw remains secure.
- Cleaning: If dust or debris accumulates in the tremolo cavity, gently clean the Arming Adjuster with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Lubrication: The internal spring mechanism is designed for smooth operation. No lubrication is typically required. If you notice any sticking, consult a qualified guitar technician.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tremolo still goes out of tune during bends. | Insufficient tension from Arming Adjuster. | Increase the tension of the Arming Adjuster's spring. Ensure proper tremolo setup (spring tension, pivot points). |
| Tremolo feels stiff or restricted. | Excessive tension from Arming Adjuster. | Decrease the tension of the Arming Adjuster's spring. Check for any obstructions in the tremolo cavity. |
| Unit is loose or rattling. | Mounting screw is loose. | Tighten the mounting screw. Do not overtighten. |
| Visible wear or damage to the unit. | Normal wear and tear or improper installation. | If performance is affected, consider replacing the unit. Ensure correct installation to prevent future damage. |
