Product Information

Full details

The Electro-Harmonix Pico Intelligent Harmony Machine is designed for musicians seeking to effortlessly add rich, diatonic harmonies to their sound in an ultra-compact format. Its key benefit lies in providing smooth, lightning-fast 2 or 3-part harmony creation in any key, acting as a perfect pocket sideman. A potential caveat for advanced users might be the limited number of interval options compared to larger, more complex units. This pedal offers essential harmony features with intuitive controls for seamless integration into any pedalboard.

FAQs

How do I select the key for the harmonies?

Use the dedicated KEY knob on the pedal. Turn it to the desired musical key (e.g., C, G, Am).

What is the difference between pressing and holding the # button?

A single press of the # button activates one harmony voice. Holding the # button down activates a second harmony voice, resulting in a 3-part harmony (your original signal plus two harmony voices).

Does this pedal come with a power supply?

No, the Electro-Harmonix Pico Intelligent Harmony Machine requires a separate 9V DC, center-negative power supply, which is not included with the pedal.

Can I use this pedal with a bass guitar?

Yes, the Pico Intelligent Harmony Machine is compatible with bass guitars and other line-level instruments. Its fast tracking should handle bass frequencies well.

How many different intervals can I choose?

The pedal offers 10 different harmonic interval options that you can select using the INTERVAL dial.

Can it create chromatic harmonies?

No, the Pico Intelligent Harmony Machine is designed to create diatonic harmonies, meaning the harmonies will always be in key with the selected musical key.

Can I save my settings?

This pedal does not have memory or preset saving capabilities. All settings are controlled via the physical knobs and buttons and are active when set.

Troubleshooting

No sound or weak signal

Ensure the power supply is correctly connected and providing sufficient voltage (9V DC). Check that all cables are securely plugged into the correct input and output jacks. Verify that the MIX knob is not turned all the way to the dry position.

Harmonies are not in key

Confirm that the KEY knob is set to the correct musical key. Ensure the # button is pressed appropriately for the desired number of harmony voices (single press for one, hold for two).

Pitch tracking is inaccurate or delayed

Ensure your instrument's signal is clean and strong. Avoid excessive effects before the Pico pedal, especially heavy distortion or pitch shifting. Check that the input level is not clipping. Make sure the pedal is running on the correct power supply.

Hum or noise

Try using a different power supply, preferably a dedicated isolated power supply, to rule out noise from other pedals. Ensure all cables are in good condition.
