BandBox Trio delivers the powerful JBL sound that makes you sound like the player you hear in your head. With a 6.5” woofer, dual tweeters, and 135 watts of clean, powerful output, BandBox Trio plays way louder than it looks. Just plug in and jam like you mean it.

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, it's 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.

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.

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).

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.

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.

Came up with something genius and don’t wanna lose it? Hit record before it disappears forever. With a USB-C output, you can connect BandBox Trio to your laptop to capture your original sound straight to your Digital Audio Workstation (DAW)—no extra interface, no extra hassle. Because when the ideas hit, you’re always ready to go.

Who needs an outlet when you’ve got range? BandBox Trio runs up to 10 hours on a charge. On a roll? Swap in a spare JBL Battery 400* and keep going like nothing happened.
