The JBL BandBox Solo is a practice amp and Bluetooth speaker in one, with a quarter inch input for plugging in a guitar or a microphone. Its headline feature is Stem AI, which separates vocals, guitar, or drums out of any track in real time, so you can mute the guitar part of a song and play it yourself over the remaining mix. It also includes built-in effects and practice tools. Best fit: guitarists who practice to recordings and want a backing track without hunting for karaoke versions, and players in apartments who need one box that handles both practice and casual listening.
Pros
- Stem AI removes vocals, guitar, or drums from a track in real time for instant backing tracks

- Doubles as a regular Bluetooth speaker when you are not practicing
- Built-in effects and practice tools, so no separate pedal is required to get started
Cons
- At around $250 it costs well above a basic practice amp, so the AI separation has to be a feature you will actually use
Frequently asked questions
Can I plug in a microphone as well as a guitar?
Yes. It has a quarter inch input that accepts an instrument or a microphone.
How well does the vocal removal actually work?
Stem separation quality varies by track. Dense mixes and heavily processed vocals are harder to isolate cleanly than sparse recordings, so expect some artifacts on difficult songs.
Does it work as a normal speaker?
Yes. It functions as a standard Bluetooth speaker with JBL's tuning when you are not using it as a practice amp.
Is it loud enough to play with a drummer?
It is a compact practice amp designed for personal practice and small spaces, not a stage amp. It will be outmatched by an acoustic drum kit.
