JBL BandBox Trio AI-Powered Practice Amp

The JBL BandBox Trio AI-Powered Practice Amp is an all-in-one portable practice amp and speaker for musicians, bands, and jam sessions. It uses Stem AI to separate vocals, drums, and guitar in real time, while 135W RMS output, amp models, effects, and a built-in mixer support full creative practice.

Built for players who want to buy a portable practice amp with Bluetooth streaming and four input channels, BandBox Trio works for guitarists, vocalists, keyboard players, electronic drums, and small group setups. Users can mute parts, isolate difficult sections, change keys, loop ideas, and shape tones without a separate mixer or audio interface.

A 6.5" woofer, dual 25 mm silk dome tweeters, and rechargeable 68 Wh battery deliver powerful JBL sound with up to 10 hours of playtime. USB-C audio interface support lets musicians record into a compatible DAW, while the JBL One app controls EQ, pitch, key, amp models, effects, practice tools, and AI stem separation.
