Compact Acoustic Preamp
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.
