Unveiled at NAMM 2026, the JBL BandBox Trio is a high-performance, 135-watt portable amplifier and speaker designed for musicians who want to "choose clarity over chaos" in their practice and performance. It is the flagship of the new BandBox series, featuring on-device Stem AI that allows for real-time instrument and vocal separation without an internet connection.
Whether you're busking on a street corner, rehearsing with a small band, or recording a demo, the BandBox Trio acts as an all-in-one solution that replaces the need for a PA system, pedalboard, and audio interface.
🌟 Section 1: The Magic of Stem AI (H2)
The standout feature of the BandBox Trio is its "brain." Powered by Stem AI, the device can take any song streamed via Bluetooth (Spotify, YouTube, etc.) and instantly separate it into individual components:
Isolate & Mute: You can mute the vocals to sing the lead yourself or silence the guitar track to practice a solo with the original backing band.
On-Device Processing: Unlike other AI tools, this happens entirely on the hardware in real time—no cloud or internet required.
Pitch & Key Shifting: Easily change the key of a song to match your vocal range or shift the pitch to match your guitar's tuning (like Drop D) without retuning your strings.
🎯 Section 2: Built-In Practice & Gigging Tools (H2)
The BandBox Trio is engineered for both individual mastery and group collaboration:
4-Channel Mixer: Features four inputs (including Hi-Z for guitar and XLR/TRS combos) and a top-mounted LCD color screen to mix levels on the fly.
Legendary Amp Models & FX: Access a digital library of vintage and modern amp tones, plus classic pedals like chorus, phaser, and lush reverbs via the JBL One app.
Practice Suite: Includes a built-in looper, drum machine, metronome, and tuner, ensuring you have everything you need in one box.
Recording Ready: Functions as a USB-C Audio Interface, allowing you to record your jams directly into your DAW on a laptop or mobile device.
