Introduction
The Electro-Harmonix MEL9 Tape Replay Machine Pedal is designed to transform your instrument's sound, replicating the distinctive tones of vintage tape-based keyboards. Utilizing advanced polyphonic technology, the MEL9 offers nine classic Mellotron-inspired sounds, allowing guitarists, bassists, and keyboardists to access a unique sonic palette without modifications to their instruments.
Key features of the MEL9 include:
- Works with guitar without requiring special pickups or MIDI implementation, accurately tracking bends, slides, and whammy dive bombs.
- Compatible with bass guitar down to the open A string, and keyboards within its polyphony (5 notes) and range (A1 to A5).
- Independent Effect and Dry volume controls enable precise mixing of the processed and unprocessed signals.
- A dedicated Dry Output jack provides the input signal at unity gain.
- The Sustain control adjusts the release time of the effect, increasing fade-out time as it is turned clockwise.

Power Supply
The MEL9 requires a 9V DC power supply with a center-negative plug. The pedal operates on 9 volts and requires approximately 100mA of current. Ensure the correct power adapter is used to prevent damage to the unit.
Connections
Connect your instrument to the INPUT jack on the right side of the pedal. Connect the EFFECT OUTPUT jack to your amplifier or next effect pedal for the processed signal. The DRY OUTPUT jack provides your original, unprocessed instrument signal at unity gain, which can be routed to a separate amplifier or signal chain if desired.

Controls and Functions

- DRY VOL Knob: This control adjusts the output volume of your original, unprocessed instrument signal. It is active for both the EFFECT OUTPUT and DRY OUTPUT jacks.
- EFFECT VOL Knob: This control adjusts the output volume of the MEL9's processed effect sound. It is active only for the EFFECT OUTPUT jack.
- ATTACK Knob: The ATTACK knob controls the fade-in speed of the effect sound. Turning it clockwise increases the time it takes for the effect to reach full volume, creating a softer, more gradual swell. Turning it counter-clockwise results in a faster, more immediate attack.
- SUSTAIN Knob: The SUSTAIN knob adjusts the decay time of the effect sound after the input signal stops. Turning it clockwise increases the length of the sustain, allowing the effect to ring out longer. Turning it counter-clockwise shortens the decay.
- PRESET Knob: This 9-position rotary switch selects one of the nine distinct Mellotron-inspired instrument sounds.
- FOOTSWITCH: This footswitch engages or bypasses the MEL9 effect. When the effect is engaged, the status LED illuminates.
Preset Descriptions
- ORCHESTRA: A rich, full orchestral sound, combining multiple string and brass elements.
- CELLO: Emulates the deep, resonant tone of a cello.
- STRINGS: A classic Mellotron string section sound, ideal for pads and melodic lines.
- FLUTE: Recreates the airy, breathy sound of a flute.
- CLARINET: Provides the distinct, reedy tone of a clarinet.
- SAXOPHONE: A vintage saxophone sound, suitable for lead melodies or harmonies.
- BRASS: A powerful brass section sound.
- LOW CHOIR: A deep, ethereal male choir sound.
- HIGH CHOIR: A bright, angelic female choir sound.
Operation
To begin using your MEL9, ensure it is properly powered and connected as described in the 'Getting Started' section. Start with the DRY VOL and EFFECT VOL knobs at the 12 o'clock position. Select a preset using the PRESET knob. Engage the footswitch to activate the effect.
Experiment with the DRY VOL and EFFECT VOL knobs to find the desired blend between your original instrument sound and the MEL9 effect. Adjust the ATTACK and SUSTAIN knobs to shape the envelope of the effect, creating anything from quick, percussive sounds to long, evolving pads.
The MEL9 is polyphonic, meaning it can process multiple notes simultaneously. For optimal tracking, ensure clean playing technique. For guitarists, using a compressor pedal before the MEL9 can help even out the signal and improve tracking consistency, especially for chords.
Maintenance
The Electro-Harmonix MEL9 pedal is a robust electronic device designed for reliable performance. To ensure its longevity and optimal function, follow these general maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners or solvents, which can damage the finish or internal components.
- Storage: Store the pedal in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- Power: Always use the specified 9V DC center-negative power adapter. Disconnect power when the pedal is not in use for extended periods.
- Connections: Periodically check all cables and jacks for wear or damage. Ensure connections are secure.
- Avoid Impact: Protect the pedal from drops or heavy impacts, which can damage internal circuitry or external controls.
Troubleshooting
If you encounter issues with your MEL9 pedal, consider the following troubleshooting steps:
- No Sound or Weak Effect:
- Verify the power adapter is correctly connected and supplying power.
- Check all instrument cables for proper connection and integrity. Try swapping cables.
- Ensure the DRY VOL and EFFECT VOL knobs are not set to minimum.
- Confirm the footswitch is engaged (status LED illuminated).
- Test the pedal in a simpler signal chain (e.g., instrument directly into MEL9, then directly to amplifier).
- Unwanted Noise or Hum:
- Ensure you are using a regulated, isolated power supply. Daisy-chaining power with other pedals can sometimes introduce noise.
- Check for ground loops in your setup.
- Try moving the pedal away from other electronic devices that might cause interference.
- Poor Tracking or Glitching:
- Ensure your instrument's output is strong and clear. Weak signals can affect tracking.
- Consider placing a compressor pedal before the MEL9 to provide a more consistent input signal, especially for guitar.
- Playing technique can influence tracking. Try to play cleanly and avoid excessive string noise.
