Maintaining proper intonation is crucial for achieving accurate and in-tune notes across the fretboard on any guitar, including those with a floating bridge. The floating bridge, also known as a tremolo or vibrato bridge, adds an extra layer of complexity to intonation adjustments. In this article, we will provide a step-by-step guide on how to adjust intonation on a floating bridge guitar, ensuring that your instrument delivers optimal tonal accuracy and playability.
Step 1: Gather the Required Tools:
Before starting the intonation adjustment process, gather the necessary tools. You will need a tuner, a screwdriver (typically a Phillips or flathead), a set of Allen wrenches (usually 1.5mm and 2.5mm), and a small ruler or measuring tape.
Step 2: Tune the Guitar:
Begin by tuning your guitar to ensure accurate reference pitch. Use a reliable tuner to achieve precise tuning for each string.
Step 3: Assess the Current Intonation:
Play each string open (without fretting) and compare it to the same string fretted at the 12th fret. Listen for any noticeable differences in pitch. If the fretted note sounds sharp or flat compared to the open string, it indicates a need for intonation adjustment.
Step 4: Locate the Bridge Saddles:
On a floating bridge guitar, the bridge saddles are the adjustable pieces that hold the strings. They determine the string length, and therefore, the intonation. Identify the individual saddle screws for each string on the bridge.
Step 5: Adjust the Saddle Position:
To adjust the intonation, start with the low E string (the thickest string) and work your way towards the high E string (the thinnest string). Using a screwdriver or Allen wrench, make small adjustments to the saddle position.
- If the fretted note is sharp compared to the open string, move the saddle slightly away from the neck (towards the bridge). This lengthens the vibrating portion of the string, lowering the pitch.
- If the fretted note is flat compared to the open string, move the saddle slightly towards the neck. This shortens the vibrating portion of the string, raising the pitch.
Step 6: Test and Re-Tune:
After making adjustments to the saddle positions, play the open string followed by the fretted note at the 12th fret. Use a tuner to check if the pitch of the fretted note matches the open string. Repeat the adjustment process as necessary until the open and 12th fret notes are in tune.
Step 7: Repeat for Each String:
Continue adjusting the saddle positions and testing the intonation for each string, moving from the A string to the D, G, B, and high E strings. Make small incremental adjustments to ensure accurate intonation across the entire fretboard.
Step 8: Fine-Tuning and Double-Checking:
Once you have adjusted the intonation for all strings, play various notes and chords across the fretboard to confirm that the instrument is properly intonated. Use your ear and a tuner as references to ensure accuracy. Make any additional fine-tuning adjustments if needed.
Conclusion:
Achieving accurate intonation on a floating bridge guitar is essential for ensuring your instrument plays in tune across the entire fretboard. By following this step-by-step guide and making small adjustments to the saddle positions, you can fine-tune the string lengths and achieve optimal intonation. Remember to test and re-tune after each adjustment to verify accuracy. With patience and attention to detail, your floating bridge guitar will deliver impeccable tonal accuracy, enhancing your playing experience.
