Keeley DynaTrem Dynamic Tremolo Pedal Instruction Manual

1. Introduction

The Keeley DynaTrem Dynamic Tremolo Pedal is an innovative effect designed to respond dynamically to your playing. Unlike traditional tremolo pedals, the DynaTrem allows your playing intensity to control the rate and depth of the tremolo effect. Play harder for a more pronounced response, or softer for a subtle, relaxed tremolo. This pedal offers an unparalleled ability to express yourself with your guitar.

2. Key Features

• Dynamic and Responsive Tremolo: Rate and Depth respond to your playing dynamics.
• Integrated Noise Reduction: Developed with advanced coding to minimize noise swells common in tremolo circuits, ensuring a quiet effect.
• Output Volume Control: Allows setting for a boost, making the effect stand out in your mix.
• True-Bypass: Ensures no tone loss when the effect is disengaged.
• Battery-Free Operation: Designed to work with any standard 9-volt, negative-tip power supply (60mA or greater).

3. Controls and Functions

1. DEPTH Knob: Adjusts the intensity or depth of the tremolo effect.
2. SHAPE Knob: Selects the waveform of the tremolo oscillation (e.g., sine, square, ramp).
3. RATE Knob: Controls the speed of the tremolo effect.
4. LEVEL Knob: Sets the overall output volume of the pedal. Can be used to achieve a volume boost.
5. Toggle Switch (Dynamic Rate/Dynamic Depth/Harmonic Trem): This three-way switch selects the dynamic response mode or engages the Harmonic Tremolo.
   • Dynamic Rate: Your playing dynamics control the tremolo speed.
   • Dynamic Depth: Your playing dynamics control the tremolo intensity.
   • Harmonic Trem: Engages a rich, harmonic tremolo effect.
6. Footswitch: Toggles the tremolo effect on or off. This pedal features True-Bypass switching.

4. Setup

To set up your Keeley DynaTrem pedal, follow these steps:

1. Power Connection: Connect a standard 9-volt DC power supply (negative tip, 60mA or greater) to the DC input jack. The pedal does not operate on batteries.
2. Input Connection: Connect your guitar or the output of a preceding effect pedal to the INPUT jack on the DynaTrem.
3. Output Connection: Connect the OUTPUT jack of the DynaTrem to your amplifier's input or the input of the next effect pedal in your signal chain.

5. Operating Instructions

Once set up, you can begin using your DynaTrem pedal:

1. Engage the Effect: Press the footswitch to activate the tremolo effect. The LED indicator will illuminate.
2. Adjust Rate and Depth: Use the RATE and DEPTH knobs to set the base speed and intensity of the tremolo.
3. Select Waveform: Turn the SHAPE knob to choose your desired tremolo waveform.
4. Choose Dynamic Mode: Use the toggle switch to select between Dynamic Rate, Dynamic Depth, or Harmonic Tremolo. Experiment with these settings to find the most expressive response for your playing style.
5. Set Output Level: Adjust the LEVEL knob to balance the effect's volume with your bypassed signal, or to provide a slight boost.
6. Experiment: The DynaTrem is designed for expressive playing. Vary your picking attack and dynamics to fully explore the pedal's capabilities.

6. Maintenance

To ensure the longevity and optimal performance of your Keeley DynaTrem 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 direct sunlight.
• Power Supply: Always use a compatible 9V DC (negative tip) power supply to prevent damage.
• Connections: Ensure all cables are securely connected but do not overtighten.

7. Troubleshooting

If you encounter issues with your DynaTrem pedal, consider the following:

• No Sound: Check all cable connections (guitar, pedal, amplifier, power supply). Ensure the power supply is correctly connected and functioning. Verify that the pedal is engaged (LED illuminated).
• Unwanted Noise: Ensure you are using a regulated 9V DC power supply. Unregulated power supplies can introduce noise. Check for faulty cables or interference from other electronic devices. The pedal features integrated noise reduction, but external factors can still contribute.
• Effect Not Engaging: Confirm the power supply is working. If the LED does not light up when the footswitch is pressed, there may be a power issue.
