The AC-Driver™ is a compact yet powerful preamp for acoustic instruments on stage. EQ and volume adjustments provide you with complete control over your tone in a rugged steel chassis with heavy-duty components that will withstand the harshest touring environments. A variable low-cut filter removes excessive low frequencies, along with a notch filter and a 180° polarity reverse switch to help eliminate feedback. The notch filter features a three-position switch that allows you to select between a normal or deep notch or remove it from the signal path altogether. A balanced XLR output feeds the PA system or a powered speaker, while a ¼” output can be used to simultaneously connect to an amplifier. The AC-Driver also features an always-on ¼” tuner output and a dedicated mute footswitch, allowing for silent tuning on stage.
