Description
Overview
The Electro-Harmonix Nano Battalion is a professional-grade, all-analog bass preamp and overdrive designed to provide bassists with an expansive palette of tones in a compact, road-ready chassis. At its core is a versatile MOSFET drive circuit, capable of delivering everything from a subtle, warm grit to fully saturated, aggressive distortion.
Beyond simple overdrive, the Nano Battalion functions as a comprehensive tone-shaping station. It combines a powerful three-band EQ with flexible signal routing options, allowing you to precisely sculpt your low end and mid-range punch regardless of whether you are using an active or passive bass.
Key Details
- MOSFET Drive Circuit: High-quality analog circuitry that provides a wide range of gain stages, from light overdrive to heavy distortion.
- Three-Band EQ: Precision control over your frequency spectrum with dedicated Treble (boost/cut above 1kHz) and Bass (boost/cut below 200Hz) knobs.
- Mid-Frequency Switch: A dedicated switch providing a 9dB boost or cut at 500Hz to help your bass cut through a dense mix or scoop out muddy frequencies.
- Flexible Signal Routing: Three distinct EQ position modes that change how the EQ interacts with the drive circuit.
- Dual Output Capability: The 1/4″ output jack supports both unbalanced signals (via standard TS cables) and balanced signals (via TRS cables) for direct connection to mixing consoles or recording interfaces.
Use Cases
- Studio Recording: Use a TRS cable to send a balanced signal directly into your audio interface, bypassing the need for a DI box while maintaining signal integrity.
- Live Performance: Utilize the MOSFET drive to add sustain and harmonic richness to your lead lines or a subtle “edge” to your rhythm playing.
- Tone Sculpting: Use the Input Mode to push specific frequencies into the distortion circuit for a more saturated, aggressive drive.
- Clean Preamping: Use the Dry Mode to shape the EQ of your clean signal without affecting the character of the distorted tones.
Installation
The Nano Battalion is a plug-and-play analog pedal. Connect your bass guitar to the input jack and your amplifier or interface to the output jack. For the best results when connecting to a PA system or recording console, use a TRS (Tip-Ring-Sleeve) cable to utilize the balanced output feature.
The pedal is powered via the included power adapter, ensuring stable voltage for the analog MOSFET circuitry.
Compatibility
- Instrument Compatibility: Fully compatible with both active and passive pickup-equipped bass guitars.
- Output Compatibility: Supports standard 1/4″ TS (unbalanced) and 1/4″ TRS (balanced) cables.
- Power: Compatible with the included manufacturer power adapter.
