Electro-Harmonix Attack Decay Tape Reverse Simulator Pedal User Manual

Introduction

The Electro-Harmonix Attack Decay is a versatile effects pedal designed to produce volume and reverse swells, backward tape sounds, artificially short staccato notes, and bowed instrument effects. This manual provides detailed instructions for its setup, operation, and maintenance.

The Attack Decay pedal is capable of generating volume and reverse swells, backward tape sounds, short staccato notes, and bowed instrument effects.

Setup

Power Requirements

The Attack Decay pedal requires a 9V DC power supply. Ensure the power supply is compatible with the pedal's specifications (center-negative, 9V DC).

Connections

• INPUT: Connect your instrument (e.g., guitar) to this jack.
• OUTPUT: Connect this jack to your amplifier or the next pedal in your signal chain.
• EXP: This input allows connection of an expression pedal or Control Voltage (CV) source for real-time control over various parameters.
• SEND/RETURN: These jacks form an effects loop. The signal within the volume envelope can be routed through external effects pedals connected to these jacks. Connect the SEND to the input of an external effect and the output of that effect to the RETURN.

Operating the Pedal

Controls Overview

The Attack Decay features several controls to shape your sound:

• VOL: Adjusts the overall output volume of the pedal.
• BLEND: Mixes the dry instrument signal with the effect signal.
• ATTACK: Controls the time it takes for the note's volume to swell from silence to full.
• DECAY: Controls the time it takes for the note's volume to fade out.
• H. VOL, TONE, HARMONIX: These knobs control the built-in Harmonix fuzz effect.
• POLY/SENS Switch: Toggles between Mono and Poly modes and adjusts sensitivity.
• PRESET Buttons (1, 2, 3): Used to save and recall up to three custom settings.
• HARMONIX/PRESET Footswitch: Engages/disengages the Harmonix fuzz or cycles through presets.
• BYPASS Footswitch: Toggles the main effect on and off.

The Attack and Decay knobs allow for precise manipulation of the volume envelope, controlling the swell-in and fade-out times of notes.

Mono and Poly Modes

The Attack Decay offers two distinct modes for volume envelope generation:

• Mono Mode: In this mode, only one volume envelope is active at a time. Playing a new note will reset the envelope, making it suitable for single-note lines or arpeggios.
• Poly Mode: When Poly mode is engaged, each note played receives its own independent volume envelope. This allows for complex, layered swells and sustained effects with chords.

The pedal's Mono and Poly modes offer different approaches to volume envelope generation, catering to single notes or chords respectively.

Harmonix Fuzz

The built-in Harmonix fuzz is fully adjustable and can be used to enhance the volume envelope effect, creating sounds reminiscent of bowed instruments. Use the H. VOL, TONE, and HARMONIX knobs to dial in your desired fuzz characteristics.

The integrated Harmonix fuzz circuit provides additional tonal shaping and can be adjusted for volume, tone, and intensity.

Effects Loop

The integrated effects loop allows you to insert other pedals into the Attack Decay's volume envelope. This means any effects placed in the loop will be affected by the Attack and Decay settings, opening up a wide range of creative possibilities.

The effects loop enables external pedals to be integrated into the Attack Decay's volume envelope, allowing for unique sound combinations.

Expression Pedal / CV Input

The EXP jack provides control over various parameters using an external expression pedal or Control Voltage (CV) source. This allows for dynamic, real-time manipulation of the pedal's settings during performance.

An expression pedal or CV input offers external control over nearly all parameters of the Attack Decay for enhanced real-time modulation.

Presets

The Attack Decay allows you to save and recall up to three custom presets. To save a preset, adjust the controls to your desired settings, then press and hold one of the PRESET buttons (1, 2, or 3) until the corresponding LED flashes. To recall a preset, simply press the desired PRESET button briefly.

Maintenance

To ensure the longevity and optimal performance of your Electro-Harmonix Attack Decay pedal, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners or solvents.
• Storage: Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
• Power: Always disconnect the power supply when the pedal is not in use for extended periods.

Troubleshooting

If you encounter issues with your Attack Decay pedal, consider the following common troubleshooting steps:

• No Sound: Check all cable connections (input, output, power). Ensure the power supply is correctly connected and functioning. Verify the BYPASS footswitch is engaged.
• Weak or Distorted Sound: Check instrument and amplifier volume levels. Ensure the power supply provides adequate voltage and current. Inspect cables for damage.
• Unexpected Behavior: If the pedal is not responding as expected, try a factory reset (refer to the full manufacturer's manual for specific instructions, if available). Ensure no expression pedal or CV source is inadvertently affecting parameters.
