The ideal action for a P Bass, which refers to the string height above the frets, varies slightly depending on your bass's fingerboard radius. Setting the correct action is crucial for comfortable playability and a clear tone, minimizing fret buzz.
Recommended P Bass String Action Guidelines
The following measurements are standard recommendations, typically taken from the bottom of the string to the top of the 17th fret:
| Fingerboard Radius | Bass Side String Height | Treble Side String Height |
|---|---|---|
| 7.25" | 7/64" (2.8 mm) | 6/64" (2.4 mm) |
| 9.5" to 12" | 6/64" (2.4 mm) | 5/64" (2 mm) |
| 15" to 17" | 6/64" (2.4 mm) | 5/64" (2 mm) |
Understanding Fingerboard Radius:
P Basses can feature different fingerboard radii. Vintage-style models often have a 7.25" radius, which is more rounded. Many modern P Basses utilize flatter radii like 9.5" or 12", which can make string bending feel easier. Knowing your bass's specific radius will help you apply the correct action measurements.
Key Considerations for Setting Action:
- Measurement Point: Always measure the string height at the 17th fret for consistent results.
- Neck Relief First: Before adjusting string action, it's essential to ensure your P Bass has proper neck relief. This slight forward bow in the neck, adjusted by the truss rod, prevents buzzing and allows for optimal string vibration. Adjusting neck relief before string height is a fundamental step in a proper bass setup.
- Playing Style: Your personal playing style will influence your preferred action.
- Aggressive players might prefer action on the higher side of the recommended range to accommodate harder plucking or picking without buzzing.
- Players with a lighter touch or those who prefer faster playing may opt for action on the lower end of the range.
- Balance and Comfort: The goal is to find a balance that feels comfortable for you, allowing for clear notes without excessive effort or unwanted fret buzz across the entire fretboard. These guidelines provide an excellent starting point, but slight adjustments based on personal preference are common.
While these measurements provide a professional standard, the "exact" ideal action is ultimately what feels most comfortable and playable for your individual style.
