Radial Engineering Tonebone AC-Driver Compact Acoustic Instrument Preamp with EQ and Output Control

The Radial Engineering Tonebone AC-Driver is a compact acoustic instrument preamp and direct box designed to deliver natural, studio-quality tone for live performance and recording. Built specifically for acoustic guitars and similar instruments, it combines high-headroom preamplification with intuitive tone shaping tools to ensure a clear, balanced, and feedback-resistant sound in any environment.

Equipped with a responsive EQ section, the AC-Driver allows precise adjustment of your acoustic tone, while the integrated low-cut filter helps reduce unwanted rumble and low-frequency buildup. A fully variable notch filter provides targeted feedback control, making it easy to eliminate resonant frequencies without affecting overall tone quality. The built-in Radial DI output ensures a clean, transformer-balanced signal for direct connection to PA systems, mixers, or recording interfaces.

Housed in a rugged, pedalboard-friendly enclosure, the AC-Driver is built for reliability on stage while remaining simple to operate. It is ideal for performing musicians who need consistent acoustic tone, feedback control, and professional direct output in one compact unit.
