  • Low-Cut, Notch & Level Knobs

The Radial Engineering Tonebone AC Driver is a studio-quality preamp in a pedal form factor. It's designed to amplify acoustic instruments on the stage, employing a Class-A buffered circuit for pristine audio. To help you achieve the tonal profile you're looking for, a low-cut filter, a notch filter, and a level knob are all supplied, as is a 180° phase switch to bust feedback.

The foot-switch mutes the pedal so you can tune quietly on stage, provided you feed your signal to a dedicated tuner by means of the dedicated 1/4" tuner output. In addition to the tuner output, a 1/4" instrument output for acoustic amplifiers is on hand, as is an XLR output with a dedicated ground-lift switch for the house PA. Heavy duty components are used throughout to ensure the pedal's durability. The pedal requires a separately-available 9 VDC power supply.
