3.1. Assembling the Double Pedal

5. Operating Your Pedal
The Pearl P932 is designed for intuitive operation. Simply apply pressure to the footboard to engage the beater with the bass drum head. The longboard design allows for various foot techniques, including heel-up and heel-down, providing versatility for different playing styles.
5.1. Adjustments
The P932 offers several adjustment points to fine-tune its performance:
- Spring Tension: Adjust the spring tension using the Click-Lock mechanism located at the base of each pedal. Higher tension provides a quicker rebound, while lower tension offers a softer feel.
- Beater Angle: Loosen the screw on the beater holder to adjust the beater's angle relative to the bass drum head. This affects the attack and feel.
- Interchangeable Cams: The pedal comes with two cam options. The Perfect Circle Cam provides a linear response, while the Eliminator-style Eccentric Cam offers an accelerated action. To change cams, carefully remove the existing cam and replace it with your preferred option, ensuring it is securely fastened.
- Powershifter Footboard: The Powershifter function allows you to adjust the footboard's position to alter leverage and power transfer. Consult the detailed diagram for specific adjustment points.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Pearl P932 pedal:
- Cleaning: Wipe down the pedals with a soft, dry cloth after each use to remove dust and debris. For stubborn grime, a slightly damp cloth can be used, followed by immediate drying.
- Lubrication: Periodically apply a small amount of light machine oil to moving parts, such as the universal joints and spring mechanisms, to ensure smooth operation and prevent squeaking.
- Inspection: Regularly check all screws, bolts, and connections for tightness. Tighten any loose components to prevent wear and ensure stability.
- Beater Condition: Inspect the beater surfaces for wear. Replace beaters if they become excessively worn or damaged to maintain consistent sound and protect your bass drum head.
7. Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pedal feels sluggish or stiff | Lack of lubrication, overtightened components, worn bearings | Lubricate moving parts, check for overtightened screws, inspect and replace worn bearings if necessary. |
| Squeaking noises | Dry joints or springs, loose components | Apply lubricant to all pivot points and springs. Tighten any loose screws. |
| Inconsistent beater response | Incorrect spring tension, loose beater, worn cam | Adjust spring tension, ensure beater is securely tightened, inspect cam for damage. |
| Pedal slides during play | Spikes not engaged, hoop clamp loose | Ensure floor spikes are extended and gripping the surface. Tighten the Roller Hoop Clamp securely. |
