1. Introduction
The DigiTech DROP is a dedicated polyphonic drop tune pedal designed to alter your guitar's tuning electronically. This pedal allows for pitch shifting from one semitone down to a full octave, eliminating the need to change guitars or retune for different musical requirements. It features a momentary/latching switch for flexible performance control and true bypass circuitry to preserve your tone when the effect is disengaged.
2. Product Overview
The DigiTech DROP pedal provides a compact solution for pitch shifting. Its intuitive design includes a selector knob for various drop tune intervals and a switch to control the footswitch behavior.

2.1 Controls and Indicators
- EFFECT SELECTOR KNOB: This knob selects the desired drop tune interval when the effect is active. Settings range from 1 semitone to a full octave, including an octave with dry signal blend.
- MOMENTARY ON/OFF SWITCH: This toggle switch determines the operation mode of the footswitch.
- When set to ON, the footswitch acts as a momentary switch. The effect is active only while the footswitch is pressed and held. Releasing the footswitch bypasses the effect.
- When set to OFF, the footswitch acts as a latching switch. Pressing the footswitch toggles the effect on or off.
- EFFECT LED: Illuminates when the effect is active.
- TRUE BYPASS FOOTSWITCH: Engages or bypasses the effect based on the MOMENTARY ON/OFF switch setting.
3. Setup
Follow these steps to connect your DigiTech DROP pedal:
- Power Connection: Connect the included 9VDC power supply to the power input jack on the pedal and then to an appropriate AC outlet.
- Input Connection: Connect your guitar or the output of a preceding pedal to the IN jack on the DigiTech DROP pedal using a standard 1/4-inch instrument cable.
- Output Connection: Connect the OUT jack of the DigiTech DROP pedal to your amplifier or the input of the next pedal in your signal chain using a standard 1/4-inch instrument cable.

4. Operating Instructions
Operating the DigiTech DROP pedal involves selecting your desired pitch shift and choosing the footswitch mode.
- Select Drop Interval: Rotate the EFFECT SELECTOR KNOB to choose the desired pitch shift setting:
- 1: Transposes guitar signal down 1 semitone.
- 2: Transposes guitar signal down 2 semitones.
- 3: Transposes guitar signal down 3 semitones.
- 4: Transposes guitar signal down 4 semitones.
- 5: Transposes guitar signal down 5 semitones.
- 6: Transposes guitar signal down 6 semitones (a tritone).
- 7: Transposes guitar signal down 7 semitones.
- OCT: Transposes guitar signal down a full octave.
- OCT + DRY: Transposes guitar signal down a full octave and blends it with the original dry signal.
- Choose Footswitch Mode: Set the MOMENTARY ON/OFF SWITCH to either ON for momentary operation or OFF for latching operation.
- Engage/Bypass Effect: Press the TRUE BYPASS FOOTSWITCH to activate or deactivate the selected drop tune effect according to the chosen footswitch mode. The EFFECT LED will indicate when the effect is active.
5. Maintenance
To ensure the longevity and optimal performance of your DigiTech DROP pedal, consider the following 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 when not in use.
- Power Supply: Always use the original or a compatible 9VDC power supply. Incorrect power can damage the unit.
- Connections: Periodically check all cable connections for wear and tear. Ensure jacks are free of dust and debris.
6. Troubleshooting
If you encounter issues with your DigiTech DROP pedal, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound when pedal is engaged. | Incorrect cable connections, faulty power supply, effect level set to zero (if applicable). | Verify all cables are securely connected. Ensure the power supply is functioning. Check the EFFECT SELECTOR KNOB setting. |
| Effect LED does not light up. | No power, faulty footswitch. | Ensure the power supply is connected and working. Test the footswitch in both momentary and latching modes. |
| Sound is distorted or unnatural. | Input signal too hot, extreme pitch shift settings, impedance mismatch. | Reduce the output level of the preceding instrument or pedal. Ensure proper impedance matching with other equipment. |
| Momentary switch not working. | MOMENTARY ON/OFF switch set to OFF. | Ensure the MOMENTARY ON/OFF switch is set to the ON position for momentary operation. |
