AC-Driver Acoustic Instrument Preamp

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.

Studio quality preamp and class-A buffer circuit

Balanced DI output to feed a PA or powered speaker

Mute footswitch for instrument changeovers

Notch filter and phase switch to reduce feedback

Great tone can be simple

The 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 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.
