Powerful JBL sound

Legendary guitar amp and effects models
JBL BandBox Trio gives you a pedalboard’s worth of effects—without lugging a single pedal. From phaser and chorus to lush reverbs that make everything feel bigger, its got all the classics built right in. Plus, legendary amp tones—from clean sparkle to face-melting distortion—everyone can lock in their go-to sound or try something new.

Built-in 4-channel mixer
Mix on the fly—no stress, no guesswork. BandBox Trio’s built-in 4-channel mixer has a big LCD screen right on top, making mid-song tweaks easy, even in low light. Four inputs let you plug in guitars, mics, keys, and even an electronic drum kit—so the whole band can sound tight.

Quality microphone effects
Built-in reverb and delay give your vocals that polished, pro sound—no extra gear needed. Just plug in, dial it in, and sound like you've got a full rack of studio effects (without hauling them around).

Onboard practice and performance tools
The JBL BandBox Trio comes with all the tools your old practice routine wishes it had. Tuner? Check. Metronome? Yep. A full-featured drum machine with presets and a looper so you can mimic a full band? You bet. And if a song’s in Drop D and you’re not feelin’ like retuning, just shift the pitch to match your vibe. Singing a little out of your range? Drop the key and pretend it was always meant to be yours. No judgment—just smarter practice, better jams, and way fewer excuses.

Big, integrated LCD color screen
The big, integrated LCD color screen lights up when you need it—so dialing in tools, amp models, and effects is a breeze. And when you’re locked in? It fades out and gets out of your way. Just like it should.
