The Nano Battalion Bass Preamp and Overdrive features a MOSFET drive circuit that delivers a broad range of distorted tones plus a three-band EQ with three EQ position modes for greater flexibility. Electro-Harmonix - Nano Battalion - Musik Utan Gränser The three-band EQ includes Treble (boost/cut above 1kHz) and Bass (boost/cut below 200Hz) controls, plus a Mid switch which provides a 9dB boost or cut at 500Hz. When a normal TS cable is connected to the output jack it delivers an unbalanced signal. Great for active or passive, pickup-equipped basses Pédale Basse Sortie Balanced TRS Electro Harmonix Nano Battalion Bass Preamp & Overdrive Pedale Basse Electro-Harmonix Nano Battalion Three signal path options determine where the EQ is applied. When a TRS cable is plugged into this jack, it outputs a balanced signal that can go directly into a mixing console or recording interface. All analog circuit with MOSFET drive for great tone and variation Boosting frequencies in this mode can drive the distortion to a more saturated state. ¼ inch output provides an unbalanced output with a TS cable or a balanced signal with a TRS cable to right into a mixing console or recording interface , Comes with an EHX9., 6DC-200 PSU User-friendly controls include Volume to set the master output level, Blend to adjust the ratio between the clean and distorted signals, Drive to control the intensity and saturation of the distortion and Tone which cuts high frequencies from the distorted signal.
