Setup
Power Connection:
- AC Adapter: Connect the optional AD-0006 AC adapter to the DC 9V input jack on the rear panel.
- Batteries: For portable use, insert four IEC R6 (size AA) batteries into the battery compartment on the bottom of the unit. Ensure correct polarity. The unit can run for over 7.5 hours on a single set of batteries.
Instrument and Output Connections:
- Connect your acoustic guitar's output to the A2's INPUT jack using a standard 1/4-inch instrument cable.
- Connect the A2's OUTPUT jack to your amplifier, PA system, or recording interface. The output is a stereo headphones out, which can be used with a 1/4-inch TS plug or a splitter for true stereo output.
Operating Instructions
Controls and Interface:
The Zoom A2 features intuitive controls for easy sound shaping and navigation.

- Footswitches: Three footswitches (MOD/EFX ON/OFF, BYPASS/TUNER, FEEDBACK CTRL ON/OFF) control various functions including effect bypass, tuner activation, and feedback control.
- Rotary Knobs: Three main rotary knobs allow simultaneous adjustment of three different parameters, similar to stompbox controls. In play mode, these adjust modulation effect mix, delay/reverb mix, and patch level.
- Display: A central LED display shows patch numbers, parameter values, and tuner information.
Effects and Modules:
The A2 offers a wide array of effects optimized for acoustic guitar:
- GLOBAL Module: Optimize frequency response for your pickup and amplifier type using AMP SELECT and PICKUP SELECT parameters.
- Equalization: Choose between a six-band linear equalizer with peaking filters (320Hz, 500Hz, 1.2kHz, 6.3kHz) and shelving filters (60Hz, 12kHz), or a two-band parametric EQ for precise adjustments.
- Feedback Control: Activate the feedback control feature to automatically or manually detect and attenuate feedback points using an effective notch filter.
- Dynamics & Filtering: Includes a limiter/compressor for peak control and effects like the resonator to emphasize specific frequency ranges.
- Modulation Effects: Features detune (for 12-string sound), flanger, phaser, and three types of chorus (mono, stereo, ensemble) to add body and depth.
- Ambience Effects: Nine types of reverb (Hall, Room, Arena, Tiled Room, Spring Reverb, Early Reflections, Slap Reverb) and an 'air effect' to simulate room ambience. Multi-tap delay and long delay (up to 5000ms) are also available.
Sound Character Simulations:
The simulation module allows you to emulate the tones of famous acoustic guitars and microphone setups:
- Acoustic Guitar Models: 12 simulations reproduce the sonic characteristics based on body size, shape, and materials.
- Mic Module: Simulates the sound of a guitar recorded through a microphone, with selectable positioning and mic type (dynamic/condenser).
Patch Management:
The A2 comes with 40 preprogrammed patches and allows you to store an additional 40 user-defined patches. The unit boasts a world-record patch change speed of 0.008 seconds, ensuring seamless transitions during live performances.
Built-in Tuner:
Activate the auto-chromatic tuner by pressing two footswitches simultaneously. High-brightness LED indicators provide clear note readout. The calibration range is 435 to 445Hz, and mute tuning is possible.
Noise Reduction (ZNR):
The integrated ZOOM Noise Reduction (ZNR) minimizes unwanted noise during playing pauses while preserving the natural decay of notes.
Integrated Drum Machine:
Practice with the built-in drum machine, featuring realistic PCM sound sources and 40 rhythm variations across different musical genres.
Optional Accessories:
- Foot Switch (FS01): Allows remote operation for tap tempo input, bank switching, drum machine start/stop, and delay hold on/off.
- Expression Pedal (FP02): Provides real-time control over effect parameters such as volume, tone, modulation rate, or delay/reverb mix level. Can also be used for manual feedback frequency detection.
Maintenance
To ensure the longevity and optimal performance of your Zoom A2 pedal, follow these maintenance guidelines:
- Cleaning: Wipe the unit with a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents.
- Storage: Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace all four AA batteries simultaneously when the low battery indicator appears or performance degrades.
- Connections: Periodically check all cable connections for wear and tear. Ensure jacks are free of dust and debris.
Troubleshooting
If you encounter issues with your Zoom A2 pedal, refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| No sound output | Check power supply (AC adapter or batteries). Ensure all cables are securely connected. Verify volume levels on the pedal, amplifier, and guitar. Check if the pedal is in bypass mode. |
| Distorted or poor sound quality | Adjust input gain to prevent clipping. Ensure correct AMP SELECT and PICKUP SELECT settings. Check for worn cables or faulty connections. Reduce effect levels if they are too high. |
| Unwanted feedback (howling) | Activate the feedback control feature. Adjust your position relative to the amplifier. Reduce overall volume. |
| Effects not engaging | Ensure the MOD/EFX ON/OFF footswitch is engaged. Check patch settings to confirm effects are enabled within the patch. |
| Tuner not working | Ensure the tuner is activated by pressing the BYPASS/TUNER footswitch. Check guitar cable connection. |
| Drum machine not playing | Ensure the drum machine is enabled and a rhythm pattern is selected. Check the drum machine volume level. |
