Boss AC-22LX Acoustic Amplifier with Air Feel Technology

A Full-Immersion Acoustic Experience

The AC-22LX presents a new concept in acoustic amplification, bringing you a full-immersion playing experience realized through advanced BOSS spatial technology. Air Feel breathes life into the dry, sterile sound of standard acoustic instrument pickups, recreating the richly detailed tones captured by classic stereo acoustic microphone setups in world-class studio settings. The AC-22LX’s inspiring voice projects far beyond its compact size, infusing your amplified sound with depth, dimension, and natural acoustic resonance.

Multi-Dimensional Tone with Air Feel

Born of intensive BOSS sound research and advanced processing technologies, Air Feel transforms your pickup’s sound with acoustic richness and dimension never possible until now. Simply plug in and enjoy your instrument’s natural acoustic character at performance volumes—without the need for microphones and audio engineering skills.

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.
