Have you ever wished you could isolate the guitar or vocals from any of your favourite songs so you can practice more easily? JBL BandBox Solo turns that into reality. This is not just a compact practice amp – it is a smart AI practice partner that helps you grow as a musician every single day.

With Stem AI technology, BandBox Solo can separate vocals, guitar and drums in real time from almost any music source. Combined with powerful JBL sound, legendary amp and effect models, and an ultra‑portable design, BandBox Solo is the perfect companion for guitarists, bassists, vocalists and drummers.

Quick Overview of JBL BandBox Solo

Real‑Time AI Stem Separation- A Breakthrough for Practice

The standout feature of JBL BandBox Solo is its ability to separate and isolate instruments from almost any song you play via Bluetooth or wired connection. Just play a track and the Stem AI engine will analyse and split it into stems for:

• Vocals

• Guitar

• Drums

From there you can:

• Mute the original guitar part and play your own version over the backing track.

• Isolate a difficult riff or passage and loop it until you have mastered it.

• Remove the lead vocal to turn any song into a high‑quality karaoke track.

• Change pitch or key in the app without retuning your instrument or forcing your voice.

This technology turns BandBox Solo into a virtual bandmate that helps you learn songs faster, practise more effectively and stay inspired.

Signature JBL Sound- Small Box, Big Tone

Even with its ultra‑compact size (only 150 x 87 x 55 mm), JBL BandBox Solo delivers an impressive 30 W RMS through its 2.25‑inch full‑range driver. You get the classic JBL sound: powerful, detailed and stable, with low distortion even at higher volumes.

The frequency response from 73 Hz to 20 kHz easily covers guitar, vocals and most practice situations. Whether you are warming up your voice, playing acoustic, electric or bass, BandBox Solo keeps up with clarity and punch.

Legendary Amp and Effect Library

BandBox Solo comes with a rich collection of amp models and effects so you can shape your own sound:

• Classic effects: Phaser, Chorus, Tremolo, Reverb – everything you need to refresh your tone.

• Amp models from vintage to modern: from warm classic rock crunch to sharp modern high‑gain tones.

You can tweak sounds directly on the unit or through the JBL One app, build virtual pedal chains and save your favourite presets for instant recall.

Built‑In Smart Practice Tools

BandBox Solo includes essential practice tools every musician needs:

• Tuner: fast and accurate tuning before every session.

• Metronome: keeps your timing locked in.

• Pitch Shift and Key Change: adjust the pitch and key of a song in seconds. If a song is too high for your voice, lower the key. If you want Drop‑style riffs without retuning, shift the pitch and keep the feel.

All controls are intuitive and quick to access so your creative flow remains uninterrupted.

Deep Control with the JBL One App

The JBL One app (iOS/Android) unlocks the full power of BandBox Solo right from your phone:

• Fine‑tune volume, tone and EQ.

• Browse, switch and customise amp models and effects.

• Access tuner, metronome, pitch shift and key change tools.

• Build and save your own virtual pedalboards.

• Update firmware to the latest version.

Everything is designed to be fast and intuitive, so you can focus on playing instead of menu diving.

Sharp LED Pixel Display- Clear and Elegant

The large LED pixel display on the front panel shows your key settings clearly whenever you need to adjust them. When you are fully immersed in playing, the display can automatically dim so it quietly steps back and lets the music take centre stage.

USB‑C Audio Interface- Capture Every Idea

The USB‑C port on BandBox Solo does more than charge. It also works as a 2‑channel audio interface. Connect it directly to your computer and record into any DAW (Cubase, Logic, Ableton, etc.) at 24‑bit / 48 kHz. No extra interface, no complex setup – when inspiration strikes, you capture it instantly.

Up to 6 Hours of Play Time- Practice Without Interruptions

With a 17 Wh Li‑ion battery, BandBox Solo offers up to 6 hours of play time after about 3.5 hours of charging. That is more than enough for long practice sessions, writing sessions or small jams without worrying about running out of power.

Silent Practice with Headphone Out

Need to practise late at night without disturbing anyone? Just plug wired headphones into the 3.5 mm output and enjoy the full sound, effects and AI features in complete privacy.

Ultra‑Compact Design- Take It Anywhere

At just 150 x 87 x 55 mm and 0.53 kg, BandBox Solo fits easily into a backpack, gig bag or even a tote. Take it to rehearsal rooms, coffee shops, writing sessions or casual jams – it is always ready to travel with you.
