Boss Katana Air, (Used)

The Boss Katana Air is a wireless desktop amplifier designed for convenience without sacrificing versatility. With 2 x 3-inch stereo speakers and 30 watts of power (when plugged in, or 20 watts on battery), it's compact yet loud enough for home playing and casual practice. Its fully wireless design—thanks to the included rechargeable transmitter—makes it easy to pick up your guitar and play without plugging in, and the amp itself can run on AA batteries or an included AC adapter.

Tonally, it offers five amp voicings from the Katana series, covering clean, crunch, lead, brown, and acoustic tones. Onboard effects include modulation, delay, reverb, and more, all editable via the Boss Tone Studio app for mobile or desktop. The amp also supports Bluetooth audio streaming, letting it double as a wireless speaker for backing tracks or general listening.

Despite its small size, the Katana Air delivers a surprisingly full sound and remains one of the most user-friendly home practice amps available, offering true plug-and-play freedom with flexible tone shaping and solid build quality.
