Radial Engineering AC Driver Instrument Pre-Amp with Direct Box

Perfect for managing your acoustic guitar signal on stage, the Radial AC-Driver is an instrument preamp and DI box that boasts outputs to both the PA and your stage amplifier.

Its intuitive controls allow you to quickly shape your acoustic instrument to sound just as natural amplified as it does unplugged. An adjustable low cut filter removes excess low boomy tones, and a 180° polarity switch is key to correcting potential feedback problems. The variable notch switch also helps cut back on troublesome frequencies. Both the unbalanced 1/4" output and the balanced XLR direct output feature level control, and a ground lift prevents ground loops over the XLR line. Finally, the latching mute switch allows you to silently switch instruments or quietly tune via the tuner output.

All of these tools are easy to use and fit in a compact stompbox. Perfect for any performing acoustic guitarist, the AC-Driver is the right choice!
