JBL BandBox Solo - AI-Powered Practice Amp & Speaker

The JBL BandBox Solo is a pocket-sized practice amp that punches way above its size. Stream any song, hit play, and onboard AI splits the vocals, drums, and guitar out in real time — so you can drop yourself into the mix, mute a part you want to play, or loop a tricky lick until it's burned into your fingers. Add JBL's classic amp models, a stack of pedal effects, and 18 watts of clean speaker, and you've got the most versatile practice tool you can fit in a backpack.

Stem AI — Jam With Your Favourite Tracks

This is the trick that makes the BandBox Solo different. Stream a track over Bluetooth and the Stem AI engine separates the vocals, drums, and guitar in real time — drop any of them out, take the solo yourself, or isolate just the part you're trying to learn. It works on the song you already love rather than some library of pre-stemmed backing tracks, which means your practice session looks like whatever music you're into.

18 Watts of Bold JBL Sound

Plug in a guitar, mic, or stream from your phone — the BandBox Solo runs everything through a 2.25" full-range driver tuned by JBL's audio team, with 18 watts of clean output and zero unwanted clipping. Frequency response runs from 73 Hz up to 20 kHz, so vocals stay crisp, drums hit, and guitar tones sit right where they should. It's loud enough to fill a bedroom, a hotel room, or the back of a tour van.

Amp Models, Pedal Effects, and Practice Tools

The Solo comes loaded with JBL's vintage and modern guitar amp models, plus a pedalboard's worth of effects — phaser, chorus, tremolo, reverb, the lot. Dial in your usual tone or stumble into something new. Onboard practice tools include a tuner, metronome, and a pitch/key shifter for when a song's in Drop D and you're not in the mood to retune (or when a vocal range is sitting a touch too high for your throat that day).

JBL One App, USB-C Audio Interface, Headphone Out

The JBL One app turns your phone into the control surface — adjust EQ, swap amp models, build custom effects chains, or run the Stem AI separation without touching the amp itself. The USB-C port doubles as a built-in audio interface, so when an idea hits you can plug straight into a laptop and record into your DAW with no extra hardware. For late-night sessions, plug in headphones (16Ω or 32Ω) and keep working without waking anyone.
