The Electro Harmonix Nano Bassballs is the exact twin of the legendary EH Bassballs. It uses two critically tuned, sweeping dynamic filters that respond sensitively to attack variations creating shifting peaks and notches to produce vowel-like overtones. The selectable distortion mode's warm harmonic distortion intensifies the overtones and deep resonance of the effect. The RESPONSE control determines how sensitive the filters are to attack dynamics. Great on bass, guitar and anything else you plug into it! Powered either by a regular 9-volt battery or a standard 9-volt DC barrel type adapter. Made in the USA.

Brand new with box and instructions.
