Professor’s Notes

Nano Battalion is for bass players who want real control over their tone in a compact footprint. It combines analog drive, flexible EQ shaping, and direct-output capability into a single box that can anchor a pedalboard or simplify a recording setup. If you need a small, dependable way to shape your sound and go from subtle grit to full drive without losing low-end authority, this is a very practical solution.

Description

The Electro-Harmonix Nano Battalion is an all-analog bass preamp and overdrive designed to give players precise control over drive character, tonal balance, and signal routing in a compact format.

Its MOSFET-based drive circuit covers a wide range, from light overdrive that adds presence and definition to heavier distortion suitable for aggressive styles. A three-band EQ with selectable midrange boost or cut allows quick shaping of low-end weight, midrange focus, and top-end clarity, while the EQ-position switch lets you determine where the EQ sits in the signal path for different tonal responses.

A balanced TRS output provides a direct connection to a console, interface, or recording system without requiring additional gear. Whether used on a pedalboard, as a front-end tone shaper, or as a compact direct solution, Nano Battalion is built to keep bass tones controlled, consistent, and easy to manage.
