More than just an octaver, the Meatbox is a thick-cut subharmonic synthesizer as well. Adding in sub notes so low that you need to be careful not to blow your speakers. A TRS out allows you to split the subharmonic synthesized signal out to the P.A. for teeth-rattling, bone wrenching, bowel-shaking, booty-quaking bass that will rock the house, literally.
