A floating bridge, also known as a tremolo bridge, is a common feature on many electric guitars, providing the ability to create pitch modulation effects and add expressive elements to your playing. Setting up a floating bridge correctly is essential to ensure your guitar stays in tune and plays well. In this guide, we will walk you through the process of setting up a floating bridge on your guitar, step by step.
Tools and Materials You’ll Need:
- Screwdriver
- Allen wrenches (if applicable)
- Guitar tuner
- Capo
- New strings (optional)
- String winder
- Pencil
- Tremolo arm (if applicable)
Step 1: Remove the Old Strings (If Necessary)
If you are setting up a new guitar or replacing strings, skip this step. If you have old strings on your guitar, use a string winder to loosen and remove them. It’s a good idea to replace old strings during this process, as new strings will help maintain tuning stability.
Step 2: Prepare the Tremolo Cavity
Most floating bridges have a cavity in the back of the guitar where the springs are located. Remove the cover to access the tremolo cavity. If your guitar has a back plate, unscrew and remove it.
Step 3: Set the Tremolo Springs
Inside the tremolo cavity, you will see the springs that counterbalance the tension of the strings. Depending on your guitar’s design, you may have two to five springs. To set up the floating bridge properly:
- For more tension and a flatter bridge angle (less floating), add or tighten springs. Use a screwdriver or an Allen wrench to turn the spring claw screws clockwise until you achieve the desired tension. Be careful not to overtighten.
- For less tension and a more pronounced floating bridge, loosen or remove springs. Turn the spring claw screws counterclockwise to reduce tension. You can remove springs one at a time until you reach the desired float.
Step 4: Adjust the Spring Claw Screws
The spring claw screws control the overall tension of the tremolo system. Ensure that the tension is balanced with the string tension for proper tuning stability.
- Tighten the screws slightly if the bridge rises too much when you use the tremolo arm.
- Loosen the screws if the bridge sinks too much or if you want more floating.
Step 5: String Installation
Install your new strings or restring your guitar following the manufacturer’s recommended procedures. Make sure the strings are properly seated in the bridge saddles and the tuning pegs.
Step 6: Tune Your Guitar
Use a tuner to bring your guitar up to pitch. Tune the strings to your desired standard tuning. As you tune, the bridge will likely move. This is normal.
Step 7: Adjust the Tremolo Springs (Fine-Tuning)
With the guitar in tune, check the bridge’s position. If it’s not parallel to the guitar body:
- If the bridge is floating too much, tighten the spring claw screws slightly to increase tension until the bridge is parallel.
- If the bridge is sitting too flat against the body, loosen the spring claw screws to reduce tension and allow the bridge to float more.
Step 8: Check Intonation and Action
Once the bridge is parallel to the body, check your guitar’s intonation and action. Adjust the saddle positions as necessary to ensure proper intonation along the entire fretboard and comfortable string action.
Step 9: Test the Tremolo Arm
If your guitar is equipped with a tremolo arm, test it to make sure it functions smoothly and returns to its neutral position after use. Adjust the tremolo claw springs if necessary for the desired responsiveness.
Step 10: Final Tune and Fine-Tuning
After adjusting the intonation and action, perform a final tuning of your guitar. Be prepared for some minor adjustments as the strings settle in during the first few hours of play.
Setting up a floating bridge on your guitar can be a precise process, but it’s essential for achieving proper playability and tuning stability. By following these steps and fine-tuning as needed, you’ll have your floating bridge set up correctly, allowing you to explore pitch modulation and other expressive playing techniques with confidence. If you’re unsure about any steps, don’t hesitate to seek assistance from a professional guitar technician or luthier to ensure your guitar’s optimal performance.
