Acoustic Instrument Preamp and Direct Box
The AC-Driver is an acoustic instrument preamp designed for use on stage, with helpful features to streamline your performance and ensure the best possible tone from your instrument.
 | Features

Great tone can be simpleThe AC-Driver allows you to obtain great sounding results in a short amount of time, with powerful easy-to-use controls that allow you to set your levels and reduce on-stage feedback. An adjustable low cut filter removes excessive low frequencies, while a 180° phase switch helps correct feedback build-up from hot spots on stage. A variable notch filter targets and removes specific problem frequencies, and a mute footswitch provides a way to silently tune on stage or change instruments without any popping or noise in the PA. |  |
AC-Driver Applications
 Feed a stage amp and FOH simultaneouslySend your acoustic signal to a stage amp and the PA simultaneously with a level control for both outputs. Remove excessive bass frequencies with the Low Cut filter control. |  Feed the PA directlySend a balanced signal directly to the PA or a powered speaker. Activate the mute switch for silent on-stage tuning or to change guitars without waiting for the FOH engineer to mute the channel. |  Reduce feedback on stageActivate the 180° phase switch to remove hot spots on stage that can cause feedback to occur. If feedback is spiking at certain frequencies, engage the notch filter and slowly adjust the variable notch frequency knob until you eliminate the feedback. |
Specifications
The AC-Driver is a compact high performance preamp with a footswitch mute control and the ability to reduce feedback on stage. A proprietary response curve has been modeled after the popular PZ-Pre, which provides a warm yet detailed sonic signature that will flatter most acoustic instruments. Extremely low noise and distortion set the AC-Driver apart, with a 14-gauge steel housing and intuitive features that provide you with complete control over your live performance.
