A floating Stratocaster bridge allows your tremolo system to move both up and down, enhancing expressive playing. To achieve this, the back of the bridge plate typically floats about 1/8 inch above the guitar's body.
Understanding the Floating Tremolo System
A floating tremolo setup on a Fender Stratocaster means the bridge assembly is poised, allowing it to pivot freely on its two pivot screws (or six vintage screws). This unique characteristic enables players to both lower and raise the pitch of notes using the tremolo arm, expanding creative possibilities beyond just dive-bombs. This delicate balance is achieved by carefully adjusting the tension between the guitar strings and the tremolo springs located in the guitar's back cavity.
Step-by-Step Guide to Floating Your Strat Bridge
Setting up a floating bridge requires patience and attention to detail. The core principle involves balancing the pulling force of the strings with the resisting force of the tremolo springs.
Essential Tools
Before you begin, gather these items:
- Electronic Tuner: For accurate pitch adjustments.
- Phillips Head Screwdriver: To adjust the tremolo spring claw screws.
- Tremolo Arm: To test the bridge's movement.
- Small Ruler or Gauge (optional): To precisely measure the 1/8-inch float.
The Adjustment Process
-
Preparation:
- Tune Your Guitar: Ensure your guitar is tuned to your preferred pitch and string gauge. String tension is a major factor, so consistency is key.
- Access the Tremolo Cavity: Carefully remove the tremolo cavity cover on the back of your Stratocaster to expose the tremolo springs and the spring claw.
-
Adjusting Spring Tension:
- The primary method to make the bridge float is to reduce the tension of the tremolo springs. This allows the string tension to pull the bridge away from the body.
- Loosen the Tremolo Spring Claw Screws: Using your Phillips head screwdriver, gradually loosen the two screws that hold the tremolo spring claw to the guitar body. Loosen them equally, a half-turn at a time, then re-tune.
- Remove Tremolo Springs (Alternative): If loosening the screws isn't enough, or if you prefer less spring tension, you can remove one or more tremolo springs. Many players find success with three springs arranged in a parallel fashion (e.g., in positions 1, 3, and 5, or symmetrically) for a floating setup, especially with standard string gauges.
- The objective is to reduce the spring tension enough so that the pulling force of the strings elevates the bridge into the desired floating position.
-
Checking the Float:
- After each adjustment (loosening screws or removing springs), re-tune your guitar fully.
- Observe the gap between the back edge of the bridge plate and the guitar's body. You are aiming for approximately 1/8 inch.
- Use the tremolo arm to gently push down and pull up on the bridge to ensure it moves freely and returns to the desired floating height after use.
-
Fine-Tuning:
- Achieving the perfect float is an iterative process. You will likely need to go back and forth between adjusting the spring claw screws, potentially adding or removing springs, and re-tuning the guitar until the 1/8-inch float is consistently maintained across all strings.
- Ensure the bridge is parallel to the guitar body, not tilted.
Why Float Your Bridge? Benefits of a Floating Tremolo
Floating your Strat bridge offers several advantages for players:
- Upward and Downward Pitch Bends: This is the most significant benefit, allowing you to both lower and raise the pitch of notes with the tremolo arm, enabling unique melodic and harmonic effects.
- Enhanced Expressiveness: Provides a wider range of vibrato, subtle shimmers, and dramatic dive bombs, adding another dimension to your playing.
- String Bends: Some players find the feel of string bending to be different, and the bridge can subtly react to bends, creating a unique sonic quality.
Considerations for a Floating Setup
While rewarding, a floating tremolo setup also comes with certain considerations:
- Tuning Stability: Floating tremolos can be more sensitive to tuning issues. Proper setup (including a well-cut and lubricated nut, correctly seated strings, and quality tuning machines) is crucial for maintaining tuning stability.
- String Gauge: Heavier string gauges exert more tension, which may require you to use more tremolo springs or tighten the spring claw screws further to achieve the desired 1/8-inch float.
- Number of Springs: While three springs are a common starting point for a floating setup, the optimal number can vary based on string gauge, personal preference, and the feel you desire from the tremolo system.
Floating vs. Decked Tremolo Comparison
| Feature | Floating Tremolo |
|---|---|
| Bridge Position | Back of bridge floats ~1/8" above body |
| Pitch Bend | Up and down (raise and lower pitch) |
| Expressiveness | High, wide range of vibrato, shimmers, dive bombs |
| Tuning Stability | Can be more sensitive; requires careful setup |
| String Bends | May slightly affect pitch of other strings (unison bends) |
