Independent shopping perspective
The Korena take
Built for acoustic players who need to manage their own stage signal, the AC-Driver combines buffering, PA output, and onstage monitoring in one compact preamp. Send a balanced line to the PA or powered speaker while using the 1/4-inch output for your own monitor. The mute footswitch keeps the tuner output active, so instrument changes and tuning can happen without audible clicks or pops. Low-cut, phase, and notch controls provide tools for dealing with excessive bass and feedback hotspots.
Strong match
Who this is for
- Acoustic stage setups needing separate feeds to a PA and personal onstage monitor.
- Performances where silent tuning or switching instruments is part of the set.
- Long cable runs or pedal chains where buffered signal handling is needed.
