Introduction
The Electro-Harmonix Lester K is a stereo rotary speaker emulator pedal designed to replicate the classic sound of a rotating speaker cabinet. It features tube-style overdrive, adjustable fast and slow modes, and fine-tunable speaker balance, offering a lush and realistic sound for both stereo and mono inputs.
Setup
To set up your Lester K pedal, follow these steps:
- Power Connection: Connect the included 9.6V power adapter to the 9V power jack on the pedal. Ensure the power source is stable.
- Audio Input: Connect your instrument (e.g., guitar, keyboard) to the MONO/L INPUT jack using a standard 1/4-inch instrument cable. For stereo input, connect the right channel to the R INPUT jack.
- Audio Output: Connect the MONO/L OUTPUT jack to your amplifier or audio interface. For stereo output, connect the right channel to the R OUTPUT jack.
- Placement: Position the pedal on a flat, stable surface, such as a pedalboard, ensuring easy access to footswitches and controls.

Operating Controls
The Lester K features several controls to shape your rotary speaker sound:
- VOL (Volume): This knob controls the overall output level of the pedal. Adjust it to match the volume of your bypassed signal or to boost your sound.
- DRIVE: This control adjusts the amount of tube-emulated overdrive. Turn it clockwise for more grit and saturation, replicating the sound of an overdriven tube amplifier.
- SLOW: This knob sets the speed of the rotary effect when in the slow mode.
- FAST: This knob sets the speed of the rotary effect when in the fast mode.
- BALANCE: This control fine-tunes the balance between the emulated horn and bass rotor elements of the rotary speaker effect. Adjust to achieve your desired tonal character.
- SPEED/BRAKE Footswitch: Toggles between the adjustable slow and fast rotary speeds. Holding this footswitch down engages the brake, gradually slowing the rotation to a stop.
- BYPASS Footswitch: Engages or disengages the Lester K effect. When bypassed, the pedal provides a true bypass signal.

Usage Tips
The Lester K is versatile and can enhance various instruments and styles:
- Organ Sounds: The Lester K excels at emulating classic rotary speaker effects for organ sounds, providing a rich, swirling texture. Experiment with different SLOW and FAST settings to achieve the desired modulation speed.
- Synth Sounds: For percussive synth sounds, the Lester K can add depth and movement. Combining it with a compressor/sustainer pedal, such as the Electro-Harmonix Soul Preacher, can further enhance the percussive attack and sustain.
- Overdrive: Utilize the DRIVE knob to introduce a warm, tube-like overdrive, adding character to your rotary sound. This can range from subtle warmth to aggressive distortion.
- Speed Transitions: The SPEED/BRAKE footswitch allows for dynamic transitions between slow and fast rotary speeds, or a gradual stop, mimicking the mechanical acceleration and deceleration of a physical rotary speaker.
Video: This demonstration showcases the Electro-Harmonix Lester K Stereo Rotary Speaker Pedal's capabilities with a keyboard. It illustrates the transition between slow and fast rotary speeds, the effect of the tube-emulated overdrive, and how the pedal can be used to enhance both organ and synth sounds, including a combination with the Soul Preacher compressor/sustainer pedal. The video also briefly mentions the Lester G model, which includes a built-in compressor and adjustable speed control for advanced users.
Maintenance
To ensure the longevity and optimal performance of your Lester K pedal:
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners or solvents.
- Storage: Store the pedal in a dry environment, away from extreme temperatures and humidity.
- Connections: Periodically check all cable connections for tightness and wear. Loose connections can lead to signal loss or noise.
- Power Supply: Always use the specified 9.6V power supply to prevent damage to the unit.
Troubleshooting
If you encounter issues with your Lester K pedal, consider the following:
- No Sound: Check all audio cables and power connections. Ensure the pedal is receiving power (LEDs should illuminate). Verify that the BYPASS footswitch is engaged.
- Weak or Distorted Sound: Check the VOL and DRIVE knob settings. Ensure your instrument's output and amplifier's input levels are appropriate.
- No Rotary Effect: Confirm the SPEED/BRAKE footswitch is not in the 'Brake' position. Adjust the SLOW and FAST knobs to ensure they are not set to minimum.
- Unwanted Noise: Ensure all cables are properly shielded and connected. Try using a different power outlet or power supply to rule out electrical interference.
