The A1 Four has numerous effects that change the sound of an instrument. Up to five can be used at the same time. Other features include a looper that can playback already recorded phrases, a rhythm machine, and a tuner. In addition, by using the MAA-1, the effects can also be applied to the sounds of instruments that are normally captured with a mic.

MAA-1 mic adapter: The effects can also be applied to an acoustic instrument by connecting a mic with an XLR connector using the MAA-1. Moreover, phantom power (+48V) can be supplied, allowing use with clip-on mics and other condenser microphones.

Effect sounds that are optimized for use with acoustic instruments: In addition to core effects from our most recent G Series, this processor includes well-regarded acoustic guitar effects from our AC Series as well as effects optimized for a variety of acoustic instruments. Performance using effects is possible free of worry about feedback by using the anti-feedback effect, Moreover, using the free Guitar Lab effect management application on a computer (Mac/Windows), you can add effects that are distributed online as well as edit and back up patch memories, for example.

30-second looper: Sound-on-sound performance is possible using the looper capable of recording up to 30 seconds. Moreover, this is convenient when using acoustic instruments that are loud unamplified because putting the looper at the beginning of the effect chain allows sound to be played once, then looped and manipulated without additional playing.

Equalization (EQ) can be quickly adjusted to suit performance conditions: In MEMORY and STOMP modes, 3 EQ (Lo/Mid/Hi) knobs and a volume (Vol) knob can be used to adjust the output. These enable quick adjustments even if the performance environment changes.

Craft sounds intuitively with easy operations: Quick intuitive sound creation is possible with operation just like a compact effect/stomp box.

Long operation on batteries:

Continuous operation for about 18 hours is possible using 4 AA batteries (when the LCD backlight is off).
