SONICAKE A-Factory Acoustic Guitar Preamp & DI with Reverb (QDS-04)

A complete acoustic front-end in one pedal. The A-Factory takes a piezo or magnetic pickup, shapes it with a three-band EQ, kills feedback with a sweepable notch filter, adds reverb for space, and sends a balanced XLR signal straight to the desk — so you can plug into any PA and sound like yourself.

Highlights

• High-impedance input voiced for acoustic pickups
• Sweepable notch filter kills feedback howl without gutting your tone
• Three-band EQ (bass, middle, treble) plus volume
• Onboard reverb with mix and decay control
• Balanced XLR DI output with ground-lift switch
• Two footswitches — preamp on/off and reverb, hold reverb for instant mute
