Radial Engineering has added the AC-Driver to its Tonebone line of interfaces – a compact acoustic instrument preamp designed for stage use, with features to streamline performance and ensure the best possible instrument tone.

Radial’s class-A buffer circuit ensures audio quality and allows use of longer cables or pedal chains without signal loss or degradation. A quarter-inch amplifier output provides a means of stage monitoring, as well as a balanced line to feed a PA system or a powered speaker. To tune silently or switch between instruments without causing clicking or popping, the mute footswitch silences everything but the tuner output on the AC-Driver.

The AC-Driver also includes an adjustable low-cut filter to remove excessive low-frequency content, along with powerful feedback-reducing features. A 180° phase adjustment switch allows management of feedback build-up from hot spots on stage, while a notch filter helps target and remove specific frequencies that are causing problems. The AC-Driver is powered using 9V adapters or multi-pedal power bricks, and its 14-gauge steel chassis and military grade circuit board ensure that it will endure the most punishing touring environments.
