JBL Bandbox Trio

The JBL BandBox Trio is an all-in-one portable practice amp and speaker built for musicians who want to practice, jam, and perform anywhere.

Its built-in Stem AI can separate vocals, guitar, and drums from your music in real time, making it easy to practice along with your favorite tracks. It also features guitar amp models, pedal effects, a 4-channel mixer, looper, drum machine, tuner, and metronome—all in one compact setup.

With 135W of output, a built-in rechargeable battery, Bluetooth, and USB audio recording, the BandBox Trio works equally well for home practice, rehearsals, small performances, or recording ideas directly to your computer.
