EMG 35TW 4-String Ceramic/Steel Dual-Mode Bass Pickup User Manual

1. Introduction

The EMG 35TW is a versatile bass pickup designed for 4-string bass guitars, offering two distinct tonal options within a single housing. This pickup combines both single-coil and humbucker configurations, allowing musicians to switch seamlessly between a rich, warm tone and a powerful, aggressive sound with pronounced mid-range. This flexibility makes the 35TW suitable for a wide range of musical styles and playing techniques.

In single-coil mode, the 35TW utilizes EMG's JCS pickup, built with ceramic and steel magnets. This configuration delivers a warm and clear tone, ideal for genres that require precision and clarity. The humbucker mode provides a robust and full-bodied sound, perfect for driving bass lines.

2. Setup and Installation

Proper installation is crucial for optimal performance of your EMG 35TW pickup. It is recommended that installation be performed by a qualified guitar technician. This section provides general guidance.

2.1 Preparation

• Ensure your bass guitar is unplugged from any amplifier or power source.
• Carefully remove the old pickup from its cavity.
• Clean the pickup cavity and ensure all wiring paths are clear.

2.2 Wiring

The EMG 35TW features a dual-mode design, requiring specific wiring to enable switching between single-coil and humbucker modes. Typically, this involves connecting the pickup to a push/pull potentiometer or a dedicated switch (not included with the pickup unless specified in a kit).

• Refer to the detailed wiring diagrams provided by EMG for your specific setup. These diagrams are available on the official EMG website.
• Connect the power, ground, and output wires according to the diagram.
• Connect the coil-splitting wire to your chosen switch (e.g., push/pull volume or tone pot).

2.3 Securing the Pickup

• Place the EMG 35TW pickup into the bass guitar's pickup cavity.
• Secure it using the provided mounting screws, ensuring it is level and at the desired height.
• Adjust pickup height to achieve optimal string balance and output.

3. Operating the EMG 35TW

The EMG 35TW offers two distinct operational modes: single-coil and humbucker. The method for switching between these modes depends on your bass guitar's wiring configuration, typically a push/pull potentiometer or a toggle switch.

3.1 Humbucker Mode

In humbucker mode, the pickup utilizes both coils, providing a full, powerful, and noise-canceling tone. This mode is characterized by:

• Increased Output: A stronger signal, ideal for driving amplifiers.
• Thicker Tone: A robust and full-bodied sound with pronounced mid-range.
• Noise Cancellation: Effective reduction of hum and interference.

This mode is excellent for rock, metal, and any genre requiring a strong, aggressive bass presence.

3.2 Single-Coil Mode

In single-coil mode, one of the pickup's coils is disengaged, resulting in a different tonal character. This mode is characterized by:

• Clearer Articulation: Enhanced clarity and definition, particularly in the higher frequencies.
• Warm Tone: A classic, articulate bass sound with good note separation.
• Lower Output: A slightly reduced signal compared to humbucker mode.

This mode is well-suited for jazz, funk, blues, and styles where a more precise and articulate bass tone is desired.

4. Maintenance

The EMG 35TW pickup is designed for durability and reliability. Minimal maintenance is required to ensure its longevity and optimal performance.

• Cleaning: Periodically wipe the pickup cover with a soft, dry cloth to remove dust and grime. Avoid using abrasive cleaners or solvents, as these can damage the finish.
• Inspection: Regularly check the wiring connections for any signs of wear or looseness. Ensure the pickup is securely mounted in its cavity.
• Environmental Factors: Protect your bass guitar and pickup from extreme temperatures, humidity, and direct sunlight, which can affect electronic components.

5. Troubleshooting

If you encounter issues with your EMG 35TW pickup, consider the following common troubleshooting steps:

5.1 No Sound or Weak Output

• Check Connections: Ensure all wiring connections (power, ground, output) are secure and correctly soldered according to the EMG wiring diagram.
• Battery Check: If your bass uses active electronics, ensure the battery is fresh and correctly installed. A weak battery can cause low output or no sound.
• Output Jack: Inspect the output jack for any loose connections or damage.
• Pickup Height: Verify that the pickup height is not set too low, which can result in weak output.

5.2 Excessive Hum or Noise

• Grounding: Ensure all components are properly grounded. Poor grounding is a common cause of hum.
• Shielding: Check if the bass guitar's control cavity is adequately shielded.
• Cable/Amplifier: Test with a different instrument cable and amplifier to rule out external equipment issues.
• Single-Coil Mode: Remember that single-coil mode, while offering a distinct tone, is inherently more susceptible to hum than humbucker mode. If hum is only present in single-coil mode, this may be normal operation.

5.3 Inconsistent Mode Switching

• Switch/Potentiometer: Inspect the push/pull pot or switch used for mode selection. Ensure it is functioning correctly and its connections are secure.
• Wiring: Re-check the coil-splitting wire connection to the switch.

If these steps do not resolve the issue, contact EMG customer support or a qualified technician.
