The Ibanez Edge Zero II bridge is a sophisticated tremolo system designed for precision, stability, and ease of use. If you own an Ibanez guitar equipped with this system, understanding its intricacies is key to unlocking its full potential and maintaining perfect playability. This guide will walk you through the essential aspects of the Ibanez Edge Zero II bridge, helping you achieve optimal setup and performance.
Understanding the Ibanez Edge Zero II Bridge System
The Ibanez Edge Zero II bridge builds upon the legacy of Ibanez’s renowned tremolo systems, offering a balance of aggressive dive-bomb capabilities and reliable tuning stability. It’s a double-locking system, meaning the strings are locked at both the nut and the bridge, providing superior tuning integrity even under heavy tremolo use. Many players appreciate the feel and responsiveness of the Ibanez Edge Zero II bridge.
Key Features of the Edge Zero II
Several design elements contribute to the effectiveness of the Ibanez Edge Zero II bridge. These features are crucial for both performance and ease of adjustment.
Zero Point System (ZPS3FE): This innovative system uses two additional springs and a stop rod to return the tremolo to the exact ‘zero’ position, significantly enhancing tuning stability. It also allows for easier string changes and tuning.
Stud Lock System: The bridge studs are designed to lock securely into place, preventing any unwanted movement and maximizing vibration transfer to the guitar body.
Low Profile Fine Tuners: Integrated into the bridge, these allow for precise tuning adjustments without unlocking the nut.
Removable Tremolo Arm: The arm can be easily removed or adjusted for tension, suiting individual player preferences.
Essential Setup and Adjustment Procedures
Proper setup of your Ibanez Edge Zero II bridge is vital for comfortable playability and stable tuning. Here’s a step-by-step approach to the most common adjustments.
String Changing on the Edge Zero II Bridge
Changing strings on an Ibanez Edge Zero II bridge differs slightly from a fixed bridge. Patience and understanding the system will make this process smooth.
Loosen and Cut Strings: Unlock the locking nuts at the headstock. Loosen the fine tuners to their middle position. Then, carefully loosen and cut the old strings.
Release String Blocks: Use the provided hex wrench to loosen the string locking screws on the bridge saddles. Remove the old string ends.
Insert New Strings: Trim the ball end off your new strings. Insert the trimmed end into the saddle’s string block and tighten the locking screw firmly.
Tune to Pitch: Stretch the strings thoroughly. Tune the guitar close to pitch using the tuning pegs. The ZPS3FE will help stabilize the bridge.
Lock the Nut: Once roughly in tune, lock the nut pads at the headstock. Use the fine tuners on the Ibanez Edge Zero II bridge for final, precise tuning.
Setting String Height (Action)
Adjusting the action on your Ibanez Edge Zero II bridge influences playability significantly. You’ll need an appropriate hex wrench for this.
Use the two large hex screws located on either side of the tremolo base plate to raise or lower the entire bridge. Turn them clockwise to raise the action and counter-clockwise to lower it. Make small, even adjustments to both screws to maintain an even string height across the fretboard. Aim for a comfortable balance between playability and avoiding fret buzz.
Intonation Adjustment
Correct intonation ensures your guitar plays in tune across the entire fretboard. This process requires a tuner and a hex wrench.
To adjust intonation on the Ibanez Edge Zero II bridge, first unlock the string saddle screw. Slide the saddle forward or backward to achieve correct intonation at the 12th fret harmonic and fretted note. Move the saddle towards the neck to sharpen the note, and towards the bridge to flatten it. Once adjusted, re-lock the saddle screw firmly. Repeat for all strings.
Adjusting Tremolo Arm Tension
The Ibanez Edge Zero II bridge features an adjustable tremolo arm tension system, allowing you to customize the feel of your tremolo arm. A small plastic collar inside the tremolo arm receptacle can be tightened or loosened. Tighten it for a firmer, less wobbly arm, or loosen it for a freer, looser feel. Experiment to find your preferred tension.
The Zero Point System (ZPS3FE) Explained
The Zero Point System (ZPS3FE) is a defining feature of the Ibanez Edge Zero II bridge, designed to enhance tuning stability and simplify setup. Understanding its function is crucial for optimal performance.
Understanding the ZPS3FE
The ZPS3FE consists of two additional springs and a stop rod that work in conjunction with the main tremolo springs. These auxiliary springs push the tremolo plate back to a precise ‘zero’ point, preventing it from floating freely. This design helps maintain tuning even if a string breaks and makes tuning adjustments easier as the bridge stays level.
Adjusting Spring Tension
The tension of the main tremolo springs, and thus the overall feel of the tremolo, can be adjusted. Access the spring claw in the back cavity of the guitar. Turning the two screws on the spring claw clockwise increases spring tension, making the tremolo stiffer and raising the bridge. Turning them counter-clockwise decreases tension, making the tremolo softer and lowering the bridge. Always make small, even adjustments to keep the Ibanez Edge Zero II bridge balanced.
Troubleshooting Common Issues
Even with a robust system like the Ibanez Edge Zero II bridge, issues can arise. Knowing how to diagnose and fix them can save you time and frustration.
Tuning Instability
If your guitar with an Ibanez Edge Zero II bridge isn’t staying in tune, consider these points:
String Stretching: New strings need to be stretched thoroughly. Pull them gently but firmly away from the fretboard several times.
Nut Pad Tightness: Ensure the locking nut pads are tightened sufficiently, but not overtightened, which can strip screws or damage the nut.
Saddle Lock Screws: Verify that the string locking screws on the bridge saddles are tight.
ZPS3FE Adjustment: Check if the ZPS3FE is properly engaged and its springs are providing adequate counter-tension.
Bridge Angle Problems
If your Ibanez Edge Zero II bridge is not sitting parallel to the guitar body, it’s likely a spring tension issue.
Adjust the screws on the spring claw in the guitar’s back cavity. If the bridge is dipping into the body, increase spring tension. If it’s pulling up too high, decrease spring tension. Make small, incremental adjustments until the bridge sits level.
Maintenance Tips for Longevity
Regular maintenance will keep your Ibanez Edge Zero II bridge in top condition for years to come.
Clean Regularly: Wipe down the bridge after each use to remove sweat and grime, which can cause corrosion.
Lubricate Pivot Points: Occasionally apply a small amount of specialized tremolo lubricant (e.g., Vaseline or Super Lube) to the pivot knife edges where the tremolo rests on the studs. This ensures smooth operation and prevents wear.
Check Screws: Periodically check all screws for tightness, including saddle screws, locking nut screws, and tremolo arm tension screws.
Spring Inspection: Inspect the tremolo springs for any signs of rust or fatigue. Replace them if necessary.
Conclusion
The Ibanez Edge Zero II bridge is a powerful and reliable tremolo system, designed to withstand aggressive playing while maintaining excellent tuning stability. By understanding its components and following this guide for setup, adjustment, and maintenance, you can ensure your Ibanez guitar performs at its absolute best. Don’t be intimidated by its complexity; with a little practice, you’ll master your Ibanez Edge Zero II bridge and unleash its full potential.
