Introducing the Boss AC-22LX, a revolutionary acoustic amplifier that redefines how you experience your guitar. With prestigious cutting-edge BOSS spatial technology, this amplifier offers a fully-immersive playing experience like never before. Say goodbye to dry and sterile sounds commonly associated with standard acoustic pickups.

The AC-22LX introduces the innovative "Air Feel", a feature that brings life and richness to your tones, replicating the intricate details captured by top-notch stereo acoustic microphone setups in renowned studio environments.

Don't be fooled by its compact size, the Boss AC-22LX delivers an immersive and expansive voice that goes beyond expectations. Experience your amplified sound with a newfound depth, dimension, and authentic acoustic resonance that will elevate your performance to new heights.

Key Features:

  • Premium Amplification for Acoustic Guitars - Offering unbelievably natural sound reproduction, the BOSS AC-22LX supplies a compact and visually appealing cabinet, where users find two custom twin-cone speakers which produce expansive stereo tones, perfect for home playing and beyond. Whether you play acoustic-electric guitar, ukulele, violin, banjo, or any other pickup-equipped stringed instrument, the AC-22LX with Air Feel technology guarantees an unmatched personal amplification experience for dedicated acoustic musicians.
  • Natural Acoustic Sounds - With the onboard Air Feel technology, the AC-22LX overcomes potential limitations and presents a groundbreaking solution for acoustic instruments in live scenarios. For the first time, this innovation brings the authentic studio microphone sound to acoustic amplification, allowing musicians to experience the true essence of their instruments without compromise or hassle.
  • Larger Than Life Tones - The amalgamation of extensive BOSS sound research and cutting-edge processing technologies, Air Feel revolutionizes the sound of your instrument's pickup, introducing a level of acoustic richness and dimension previously unattainable. With effortless plug-and-play functionality, you can now experience your instrument's natural acoustic character at performance volumes, all without the necessity of microphones or audio engineering expertise.
  • Shape Your Sound - The AC-22LX offers a versatile range of features for both the Guitar/Instrument and XLR Mic channels. The Guitar/Instrument channel includes five Air Feel settings, a three-band EQ, and reverb and combined reverb/chorus effects to add spatial depth. Whereas on the XLR Mic channel, you have the option of selecting phantom power for condenser mics, a two-band EQ, and dedicated reverb for independent processing. Not only that but with 15 onboard memories, you can conveniently store and recall different setups tailored to various songs and instruments. To further enhance control, the AC-22LX Editor provides even more extensive options, allowing you to switch reverb types, access detailed effect parameters, and perform various other adjustments.
  • Onboard Rhythms - The AC-22LX is equipped with a built-in Rhythm Box, designed to add excitement to practice sessions and elevate live performances. Offering five instrument types, featuring percussion and full drum set sounds, all enhanced by BOSS spatial technology to create a dynamic and immersive rhythmic experience that fills the surrounding space with vibrant energy. You can select from 15 different patterns and easily set up the perfect groove using the tap tempo button. Additionally, for those seeking more versatility, the AC-22LX Editor allows the customisation of patterns with 119 variations, giving you even more control over the rhythmic elements to suit your preferences and style.

Air Feel Types:

  • Dry - Unprocessed tone that amplifies the direct pickup sound.
  • XY - Recreates a coincident pair technique that uses two mics placed in an XY pattern. This focused stereo sound provides a good balance between the strings and body resonance, making it ideal for rhythmic chord strumming and muted playing.
  • AB - Recreates a spaced-pair mic technique for a wide stereo sound with naturally expanded acoustic resonance. This big, full presentation is great for solo guitar and fingerpicking styles.
  • ORTF - This special stereo mic technique combines elements of the XY and space-pair approaches. It produces a focused tone with increased depth and body resonance.
  • Mid-Side - This classic technique produces a well-defined sound with a wide stereo spread. It adds a sense of distance, providing a nice ensemble blend with vocals and other instruments.
