The rich, detailed tone of an acoustic guitar is created by a delicate triple harmony of strings, neck, and body. But a piezo or magnetic pickup never captures the full body resonance, often resulting in thin sound dominated by the strings. This tendency can't be fully compensated with a conventional preamp equalizer.

The A2 series incorporates 24-bit / 96 kHz sampling and sophisticated sound modeling technology to process the line signal from the pickup, adding a lush body tone and the spatial ambience that is created by mic recording. Even when playing through an amplifier or PA speaker, the resonance of the guitar body is restored, allowing the natural acoustic sound to shine through.

Select optimum characteristics to match pickup and amp model
The GLOBAL module that controls settings for the entire unit combines a pair of parameters called AMP SELECT and PICKUP SELECT.

AMP SELECT: Choose from three settings (combo, bright combo, stack) and eliminate the excessive treble that can ruin the sound when playing an acoustic guitar through an amp.
PICK UP SELECT: Besides piezo and magnetic for acoustic guitars, electric guitar pickup settings such as single-coil and humbucker settings are available, allowing you to use the unit as an acoustic guitar simulator.

Expression pedal adds further versatility to your guitar play
The built-in expression pedal is a great way to control effect parameters in real time. Besides adjusting the volume or the tone of a simulation effect, the pedal can be used for manual detection of feedback frequency, controlling the modulation rate, or adjusting the delay/reverb mix level. The dedicated PEDAL ASSIGN key and status LED indicators make it easy and quick to select the effect to control. Effect on/off switching is also possible by pushing the pedal fully down.

USB port enables computer recording
The USB port allows the unit to function as an audio interface for a computer. Simply connect a USB cable to utilize the high-quality sound of the A2.1u in a computer-based recording system.
