Product Information

Full details

The Electro-Harmonix Nano Battalion is designed for bassists seeking a wide range of analog tones, from subtle overdrive to aggressive distortion, with extensive EQ control. Its primary benefit is delivering versatile, high-quality sound shaping in a compact pedal. A potential caveat is that the routing of the EQ can significantly alter the character of the distortion, requiring experimentation to achieve desired results.

FAQs

What type of power supply does the Nano Battalion require?

It requires a standard 9V DC power supply with a center-negative plug, drawing at least 100mA. A power supply is not included.

How does the 'Input Mode' for the EQ differ from 'Distortion Mode'?

In Input Mode, the EQ affects the signal *before* it hits the distortion circuit, influencing how the distortion itself sounds. In Distortion Mode, the EQ affects the signal *after* the distortion, shaping the final distorted tone.

Can I use the Nano Battalion for guitar?

While primarily designed for bass, the Nano Battalion can be used for guitar. However, its EQ and drive characteristics are voiced specifically for the lower frequencies of a bass guitar, so results may vary.

What is the purpose of the balanced output?

The balanced output, accessible with a TRS cable, provides a cleaner signal with reduced noise over longer cable runs and allows for direct connection to professional audio equipment like mixing consoles and recording interfaces.

How does the Mid switch affect the sound?

The Mid switch provides a substantial 9dB boost or cut precisely at 500Hz, a crucial frequency for bass guitar presence and definition. This allows for significant tonal sculpting in the midrange.

Does the pedal include a power supply?

No, the Electro-Harmonix Nano Battalion does not include a power supply. You will need to purchase a compatible 9V DC adapter separately.

Troubleshooting

No sound output

Check that the power supply is connected and functioning. Verify all cable connections between the bass, pedal, and amplifier/interface. Ensure the input and output jacks are clean.

Distortion is too harsh or muddy

Adjust the Treble, Bass, and Mid controls. Experiment with the three EQ signal path options (Distortion, Input, Dry) to find the desired tonal character. Reduce the drive level if necessary.

Balanced output not working

Ensure a TRS cable is being used to connect to the output jack and the receiving device (mixer/interface) is configured to accept a balanced signal.

Amp hum or noise

Try a different power supply or a dedicated isolated power supply. Ensure all cables are of good quality and properly shielded. Check for nearby electronic interference.

Pros and Cons

Pros

  • Extremely versatile tone-shaping capabilities for bass.
  • Robust analog circuitry for natural sound.
  • Flexible EQ routing options allow for unique distortion textures.
  • Balanced output simplifies direct recording or live sound connections.
  • Durable and compact design.

Cons

  • The Mid switch can be quite aggressive, requiring careful adjustment.
  • Experimentation is needed to fully understand and utilize the EQ modes.
  • Does not feature digital programmability or presets.
  • Requires a standard 9V power supply (not included).

Setup, Compatibility & Care

Setup:

  1. Connect your bass guitar to the input jack using a standard 1/4 inch instrument cable.
  2. Connect the output jack to your amplifier or directly to a mixing console/audio interface using either a standard 1/4 inch cable (unbalanced) or a TRS cable (balanced).
  3. Connect a standard 9V DC, center-negative power supply (minimum 100mA, not included) to the power input.

Compatibility:

  • Compatible with all standard electric bass guitars.
  • Works with any bass amplifier.
  • The balanced output requires a TRS (Tip-Ring-Sleeve) cable for full functionality when connecting to mixers or interfaces. Standard TS (Tip-Sleeve) cables will provide an unbalanced signal.

Care:

  • Keep the pedal away from excessive moisture and extreme temperatures.
  • Clean the exterior with a dry or slightly damp cloth only. Do not use abrasive cleaners.
  • Ensure the power supply is disconnected before cleaning.
