hey everybody, i have a question about my amp. it is a hifonics boltar. it has this knob that im unsure about what it does... the very end of the knob is labelled 0.2v and the very first of the knob is labelled 9v. does this allow me to change the volts for some reason? what sound differences does this make? what should i set it on? any help is appreciated
