JBL BandBox Trio – AI Practice Amp, Portable PA Speaker & 4-Channel Mixer for Guitar, Vocals and Band Jams

The JBL BandBox Trio is an all-in-one, AI-powered practice amp and speaker that transforms how you practise, jam, and create. Stream any track and BandBox Trio uses real-time AI stem separation to split instruments and vocals instantly—so you can mute parts, isolate tricky solos, or change key and pitch. It’s like having bandmates who are actually playing with you.

Real-Time AI Stem Separation for Smarter Practice

Put yourself in the mix. Whatever the song, BandBox Trio separates vocals, drums, and guitar in real time so you can take the solo, front the band, or lock in with the groove. Isolate the hard parts until they’re second nature, then jump back into the full track feeling tight and confident.

Powerful JBL Sound with 135W Output

BandBox Trio delivers powerful JBL sound with a 6.5" woofer, dual tweeters, and 135 watts of clean output. It plays louder than it looks—ideal for home practice, rehearsals, and portable performance setups.

Guitar Amp Models and Built-In Pedal Effects

Get legendary tones without lugging a pedalboard. The JBL BandBox Trio includes classic guitar amp models from clean sparkle to heavy, high-gain distortion, plus must-have effects like phaser, chorus, and lush reverb. Dial in your go-to tone or experiment with new sounds for riffs, jams, and songwriting.

Built-In 4-Channel Mixer for Full Rig Control

Ready to jam with others or run a complete setup? BandBox Trio includes a built-in 4-channel mixer with a large LCD screen for quick adjustments, even in low light. With four inputs you can plug in guitars, microphones, keys, and even an electronic drum kit—perfect for rehearsal rooms, small setups, and on-the-go sessions.

Microphone Effects for Polished Vocals

Add instant studio-style polish with built-in reverb and delay on vocals. Plug in a mic, dial it in, and get a bigger, more professional sound without extra gear.

Onboard Practice and Performance Tools

BandBox Trio brings together essential tools for practice and performance: a tuner, metronome, drum machine with presets, and a looper to build full-band style parts. Use pitch shift and key change to match songs without retuning or to bring tracks into a comfortable singing range.

Big Integrated Colour LCD Screen

The integrated colour LCD screen makes it easy to navigate tools, amp models, effects, and mixer settings. It lights up when you need it and fades back when you’re focused on playing.

Built-In USB Audio Interface for Recording

Capture ideas instantly. With a USB-C output, BandBox Trio connects to your laptop and records straight into your DAW. No external audio interface required—ideal for songwriting, quick demos, and recording your original jams.

JBL One App Control

Use the JBL One app to control volume, EQ, pitch, key, tone, and custom pedal chains from your phone. Swap amp models, tweak effects, manage practice tools, and run AI stem separation—right from the app.
