how to intonate a floyd rose

3 min read 18-01-2025

The Floyd Rose tremolo system is renowned for its expressive pitch-bending capabilities, but setting it up correctly—especially intonation—can be tricky. This guide will walk you through the process of intonating your Floyd Rose, ensuring your guitar plays perfectly in tune across the fretboard. Mastering this skill will significantly improve your playing experience.

Understanding Intonation

Intonation refers to the accuracy of the pitch of each string at different frets. A properly intonated guitar will play in tune across the entire fretboard. With a Floyd Rose, this process is slightly more complex due to the floating bridge's design. Incorrect intonation leads to notes being sharp or flat, particularly noticeable when bending strings or playing higher up the neck.

Tools You'll Need

Before you begin, gather the following tools:

A chromatic tuner: Essential for accurate pitch measurement. Digital tuners are recommended for their precision.
Screwdrivers: You'll need the correct size(s) for adjusting the intonation screws on your Floyd Rose bridge.
Allen wrenches: These are often needed for fine-tuning the saddle height and other bridge adjustments. Check your guitar's manual for specifics.
Guitar picks: These are needed to create some string vibration while tuning.

Steps to Intonate a Floyd Rose

This process requires careful attention to detail. It may take several iterations to perfect intonation across all strings.

1. Lock Your Tremolo Arm: Ensure your tremolo arm is securely locked in place to avoid any unintentional pitch shifts during intonation.

2. Tune Your Guitar to Pitch: Accurately tune all six strings to your desired tuning using your chromatic tuner. Use the tuning pegs to do so, as you don't want to alter the Floyd Rose's initial position during this step.

3. Intonating Each String: This is done individually for each string, focusing on the 12th fret harmonic and fretted note.

12th Fret Harmonic: Pluck the 12th fret harmonic of the string. Your tuner should show its pitch.
12th Fret Fretted Note: Now fret the string at the 12th fret. The fretted note should match the harmonic pitch. If not, adjust the intonation screw for that string:
- Fretted Note Sharp: Turn the intonation screw clockwise to shorten the string's vibrating length.
- Fretted Note Flat: Turn the intonation screw counter-clockwise to lengthen the string's vibrating length.
Repeat: Repeat this process for each string. Make small adjustments, re-tuning between each adjustment to avoid cumulative inaccuracies. It's important to be patient and make very small adjustments at a time.

4. Fine-Tuning: Once you've intonated each string to the best of your ability, re-tune your guitar and play a few chords and scales across the fretboard. Make additional fine adjustments as needed. Listen carefully for any inconsistencies.

5. Verify Intonation: After completing your intonation process, play your guitar at different positions across the neck. Listen for any instances where notes are slightly off. If necessary, go back through the individual string intonation to refine it further.

Common Mistakes to Avoid

Over-adjusting: Make small adjustments to the intonation screws. Large adjustments can quickly throw your intonation off.
Ignoring the 12th Fret Harmonic: The harmonic serves as a more precise reference point compared to the open string, as the harmonic does not suffer from fretting errors.
Neglecting String Stretching: Newly installed strings will stretch over time; re-intonate the guitar after breaking in the new strings.

Maintaining Intonation

Your Floyd Rose will require occasional intonation adjustments, depending on string changes, temperature, and humidity. Regularly check the intonation of your guitar, especially after changing strings.

Conclusion

Intonating a Floyd Rose tremolo system may seem daunting at first, but with careful attention and patience, you can achieve perfect intonation across your guitar's fretboard. By mastering this skill, you'll unlock the full potential of your Floyd Rose, enhancing your playing experience and ensuring your guitar sounds its best. Remember to always make small, incremental adjustments and re-tune frequently for the most accurate results.
