Guitar World Verdict

The Waza-Air setup changes the game for the practice setup, with a wireless headphones system that offers three-dimensional sound, and a cornucopia of amp models and effects plus Bluetooth audio streaming. It might well be the most portable and finest practice solution ever.

The say "Practice makes perfect" but a guitarist's practice routine can be a dull affair, especially when it is just you stuck in a room with your headphones and amp. It would be much more exciting if something allowed you to have those practice sessions anywhere, right?

Well, that's where the Boss Waza-Air comes in. Following on the Boss Katana-Air's success – an amp Boss called “the world’s first totally wireless guitar amplifier” – the company is pushing the envelope further here with a personal wireless guitar headphone amp that integrates a gyro sensor that tracks your head movement and spatial technology to offer a truly three-dimensional, “amp-in-room” experience.

Paul is one of the few gear editors who has actually played and owned nearly all the original gear that most guitarists wax poetically about, and has survived this long by knowing every useless musical tidbit of classic rock, new wave, hair metal, grunge, and alternative genres. When Paul is not riding his road bike at any given moment, he remains a working musician, playing in two bands called SuperTrans Am and Radio Nashville.
