JBL BandBox Trio AI-Powered Practice Amp and Speaker - Black

Practicing alone no longer has to feel like practicing alone, and the JBL BandBox Trio transforms solo sessions into full-band experiences with intelligent, performance-ready design. This all-in-one, AI-powered practice amp and speaker uses real-time Stem AI to separate vocals, drums and instruments from any streamed track, letting you mute parts, isolate solos or shift keys instantly. With 135W of JBL sound from a multi-driver speaker system, built-in guitar amp models and effects, and a four-channel mixer for mics and instruments, BandBox Trio is built to practice smarter and jam harder. Add onboard practice tools, USB recording, app-based control and up to 10 hours of battery-powered playtime, and you’ve got a portable creative hub that’s ready wherever inspiration strikes.

Real-Time Stem AI for Smarter, More Musical Practice

At the heart of BandBox Trio is its Stem AI technology, which analyzes music in real time and separates vocals, drums and guitar as you stream. This lets you step into the mix however you want—take the solo, front the band or lock in tightly with the rhythm section. Difficult passages can be isolated and looped until they’re second nature, making BandBox Trio an invaluable tool for focused practice, songwriting and learning songs faster, all while keeping the experience musical and inspiring.

Powerful JBL Sound in a Compact, Go-Anywhere Design

Despite its portable size, BandBox Trio delivers the bold, room-filling sound JBL is known for. A 6.5" woofer, dual silk-dome tweeters and 135W of clean output provide punchy lows, clear mids and detailed highs that translate whether you’re practicing quietly or turning it up. Designed to play much louder than it looks, BandBox Trio is equally at home in a garage rehearsal, a backyard jam or a casual performance on the go.

Versatile Amp Models and Effects—No Pedalboard Required

BandBox Trio packs a wide range of classic guitar amp tones and must-have effects directly into the amp, eliminating the need for extra gear. From clean sparkle and warm crunch to aggressive, high-gain distortion, its amp models cover everything from subtle practice tones to full-on jam sounds. Built-in effects like chorus, phaser, reverb and delay let you shape your tone quickly, encouraging experimentation and helping you dial in a sound that feels inspiring every time you plug in.

Built-In Mixer, Practice Tools and Performance Features

A four-channel mixer with an integrated color LCD makes BandBox Trio far more than a solo practice amp. You can plug in guitars, microphones, keyboards or even an electronic drum kit and adjust levels on the fly, making it easy to rehearse with others or perform stripped-down sets. Onboard tools like a tuner, metronome, drum machine, looper, pitch shifting and key adjustment turn BandBox Trio into a complete practice and performance hub that adapts to your needs.

Record, Control and Play Anywhere

When inspiration strikes, BandBox Trio is ready to capture it. A built-in USB-C audio interface lets you record directly into your DAW without extra hardware, while the JBL One app gives you wireless control over EQ, effects, amp models and AI features. With up to 10 hours of battery life and a swappable battery option, BandBox Trio is built to keep up wherever creativity takes you—making it a powerful, flexible companion for practicing, jamming and creating on your own terms.
